How to Find X in an Algebra Question

••• Jupiterimages/Photos.com/Getty Images

Algebra is a type of mathematics that introduces the concept of variables representing numbers. "X" is one such variable used in algebraic equations. You can find "x" or solve the equation for "x" by isolating the "x" on one side of the algebraic equation. To solve for "x", you need to understand the basic rules of algebraic operations.

    Isolate "x" on one side of the algebraic equation by subtracting the sum that appears on the same side of the equation as the "x." For example, in the equation "x + 5 = 12", rewrite the equation as "x = 12 - 5" and solve for "x." The solution is "x = 7."

    Isolate "x" on one side of the algebraic equation by adding the negative number that appears on the same side of the equation as the "x." For example, in the equation "x - 5 = 12", rewrite the equation as "x = 12 + 5" and solve for "x." The solution is "x = 17."

    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."

    Isolate "x" on one side of the algebraic equation by multiplying the number that appears on the same side of the equation as part of an "x" fractional component. For example, in the equation "x / 2 = 3, rewrite the equation as "x = 2 x 3" and solve for "x." The solution is "x = 6."
