Two-Step Equations

Front

What is a two-step equation?

Back

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

Front

Solve for x: 4x + 7 = 23

Back

x = 4

Front

What is the first step to solve the equation: 11 - 3x = 44?

Back

Subtract 11 from both sides.

Front

Solve for x: 3(x + 2) = 15

Back

x = 3

Front

How do you isolate x in the equation: x - 62 = 123?

Back

Add 62 to each side.

Front

What does it mean to isolate a variable?

Back

To isolate a variable means to manipulate the equation so that the variable is on one side and all other terms are on the opposite side.

Front

What is the solution to the equation: 2x + 5 = 15?

Back

x = 5

Front

What is the first step to solve the equation: 5x - 3 = 12?

Back

Add 3 to both sides.

Front

Solve for a: 2a + 4 = 10

Back

a = 3

Front

What is the purpose of using inverse operations in solving equations?

Back

Inverse operations are used to undo the operations applied to the variable, helping to isolate it.
