Solving One- and Two-Step Equations

Front

What is a one-step equation?

Back

An equation that can be solved in one operation, such as addition, subtraction, multiplication, or division.

Front

What is a two-step equation?

Back

An equation that requires two operations to solve, typically involving both addition/subtraction and multiplication/division.

Front

How do you isolate a variable in an equation?

Back

By performing inverse operations to both sides of the equation until the variable is alone on one side.

Front

What is the first step to solve the equation: 3x + 5 = 20?

Back

Subtract 5 from both sides to get 3x = 15.

Front

What is the solution to the equation: 2x - 4 = 10?

Back

x = 7.

Front

What does it mean to 'balance' an equation?

Back

To keep both sides of the equation equal by performing the same operation on both sides.

Front

What is the first step to solve the equation: x/4 = 3?

Back

Multiply both sides by 4 to isolate x.

Front

What is the solution to the equation: 5x + 2 = 17?

Back

x = 3.

Front

What is the first step to solve the equation: x - 12 = -14?

Back

Add 12 to both sides to get x = -2.

Front

What is the solution to the equation: 3/4m - 3 = 9?

Back

m = 16.
