In algebra, it is easy to find the third value when two values are given. Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side.
How do you find the X in an equation?
To find the x-intercept of a given linear equation, plug in 0 for ‘y’ and solve for ‘x’ . To find the y-intercept, plug 0 in for ‘x’ and solve for ‘y’. In this tutorial, you’ll see how to find the x-intercept and the y-intercept for a given linear equation. Check it out!
How do I calculate X?
Isolate “x” on one side of the algebraic equation by dividing the number that appears on the same side of the equation as part of “x.” For example, in the equation “12x = 24”, rewrite the equation as “x = 24 / 12” and solve for “x.” The solution is “x = 2.”

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 the 3 rules of algebra?
There are many laws which govern the order in which you perform operations in arithmetic and in algebra. The three most widely discussed are the Commutative, Associative, and Distributive Laws . Over the years, people have found that when we add or multiply, the order of the numbers will not affect the outcome.
What is the basic rule 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 is area formula?
