The second step is
to isolate the variable by multiplication or division
. In the problem, x is being multiplied by two. The inverse of multiplication is division, so you should divide both sides of the equation by 2.
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.
What is the second step to solving this equation 9x 23 49?
9x – 23 =
49
.
A
.
Subtract 23 from both sides
.
What is a 2 step equation example?
Sal solves the equation
-16 = x/4 + 2
. It takes two steps because he first has to subtract 2 from both sides and then multiply both sides by 4.
What are the steps to solving this equation?
- 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.
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. If we subtract the same number from both sides of an equation, both sides will remain equal.
How do you solve an equation with 2 variables?
- Step 1: Solve one of the equations for one variable.
- Step 2: Substitute this in the other equation to get an equation in terms of a single variable.
- Step 3: Solve it for the variable.
- Step 4: Substitute it in any of the equations to get the value of another variable.
What is the golden rule for solving equations?
Do unto one side of the equation, what you do to the other!
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
