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 a two-step equation?

Back

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

Front

What is the first step to solve the equation 11b + 7 = 40?

Back

Subtract 7 from both sides to get 11b = 33.

Front

What is the second step to solve the equation 11b = 33?

Back

Divide both sides by 11 to find b = 3.

Front

Solve the equation 4x + 22 = -34.

Back

x = -14.

Front

What is the first step to solve the equation x/3 + 5 = -1?

Back

Subtract 5 from both sides to get x/3 = -6.

Front

What is the second step to solve the equation x/3 = -6?

Back

Multiply both sides by 3 to find x = -18.

Front

Solve the equation 7k - 14 = 42.

Back

k = 8.

Front

What is the first step to solve the equation x/5 - 13 = 20?

Back

Add 13 to both sides to get x/5 = 33.

Front

What is the second step to solve the equation x/5 = 33?

Back

Multiply both sides by 5 to find x = 165.
