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

What is the first step to solve the equation 3c + 5 = 23?

Back

Subtract 5 from both sides to isolate the term with the variable: 3c = 18.

Front

What is the second step to solve the equation 3c + 5 = 23?

Back

Divide both sides by 3 to find c: c = 6.

Front

How do you isolate the variable in the equation x - 4 = 12?

Back

Add 4 to both sides to isolate x: x = 16.

Front

What is the solution to the equation 2x - 3 = 1?

Back

Add 3 to both sides to get 2x = 4, then divide by 2 to find x = 2.

Front

Back

Multiply both sides by 4 to eliminate the fraction: x - 3 = 40.

Front

Back

Add 3 to both sides to find x: x = 43.

Front

What does it mean to 'solve for x'?

Back
