To solve a two-step inequality,
undo the addition or subtraction first, using inverse operations , and then undo the multiplication or division
. The inverse operation of addition is subtraction and vice versa. Similarly, the inverse operation of multiplication is division and vice versa.

How do you solve an inequality step by step?
- Add the same number on both sides.
- From both sides, subtract the same number.
- By the same positive number, multiply both sides.
- By the same positive number, divide both sides.
- Multiply the same negative number on both sides and reverse the sign.

What are the 4 steps to solving an equation?
We have 4 ways of solving one-step equations:
Adding, Substracting, multiplication and division
. If we add the same number to both sides of an equation, both sides will remain equal.
How do you simplify one step inequalities?
Many simple inequalities can be solved by
adding, subtracting, multiplying or dividing both sides until you are left with the
variable on its own. But these things will change direction of the inequality: Multiplying or dividing both sides by a negative number. Swapping left and right hand sides.
How do you read an inequality word problem?
- at least – means greater than or equal to.
- no more than – means less than or equal to.
- more than – means greater than.
- less than – means less than.

How do you write and solve an inequality from a word problem?
- Read through the entire problem.
- Highlight the important information and key words that you need to solve the problem.
- Identify your variables.
- Write the equation or inequality.
- Solve.
- Write your answer in a complete sentence.
- Check or justify your answer.
What is the golden rule for solving equations?
An equation is like a balance scale. If we put something on, or take something off of one side, the scale (or equation) is unbalanced. When solving math equations, we
must always keep the ‘scale’ (or equation) balanced so that both sides are ALWAYS equal
.
What are two basic rules for solving algebraic equations?
In algebra 1 we are taught that the two rules for solving equations are
the addition rule and the multiplication/division rule
. The addition rule for equations tells us that the same quantity can be added to both sides of an equation without changing the solution set of the equation.
What are the rules for solving equations?
- Simplify each side of the equation by removing parentheses and combining like terms.
- Use addition or subtraction to isolate the variable term on one side of the equation.
- Use multiplication or division to solve for the variable.
How do you solve one step equations and inequalities?
One-step inequalities are solved by
multiplying both sides of the equation by a number
. One-step inequalities are solved by dividing the same number into both sides of the equation. One-step inequalities are solved by multiplying the reciprocal coefficient of the term with a variable to both sides of the equation.
What are 2 step equations?
A two-step equation is
an algebraic equation that takes you two steps to solve
. You’ve solved the equation when you get the variable by itself, with no numbers in front of it, on one side of the equal sign.
How do you solve and graph one step inequalities?
One-step inequalities are solved by
multiplying both sides of the equation by a number
. One-step inequalities are solved by dividing the same number into both sides of the equation. One-step inequalities are solved by multiplying the reciprocal coefficient of the term with a variable to both sides of the equation.
