Two Step Equations

A two-step equation is an algebraic equation that requires two operations to solve for the variable.

To isolate a variable, perform inverse operations in the reverse order of operations used in the equation.

Subtract 1 from both sides to get -4x = 20.

n = -5.

First, subtract 4 from both sides to get 5x = -10, then divide by 5 to find x = -2.

Add 5 to both sides to get x/2 = 8.

First, subtract 17 from both sides to get 2y = 38, then divide by 2 to find y = 19.

Inverse operations are operations that undo each other, such as addition and subtraction or multiplication and division.

Checking your solution ensures that the value you found satisfies the original equation.

A two-step equation typically has the form ax + b = c, where a, b, and c are constants.
