Solving Two-Step Equations Practice #3

Front

What is a two-step equation?

Back

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

Front

How do you isolate a variable in an equation?

Back

To isolate a variable, perform inverse operations to both sides of the equation until the variable is alone on one side.

Back

Multiply both sides by 2 to find x.

Front

Solve the equation: 7k - 14 = 42.

Back

k = 8.

Front

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

Back

Inverse operations help to 'undo' the operations applied to the variable, allowing us to isolate it.

Front

Back

First, subtract 27 from both sides, then multiply by -15 to find x.

Front

Back

x = -168.

Front

What does it mean to check your solution in an equation?

Back

Checking your solution means substituting the value back into the original equation to verify that both sides are equal.

Front

Solve the equation: -5 - 6a = -59.

Back

a = 9.
