Two Step Equations Review

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 inverse operations in the reverse order of operations used in the equation.

What is the first step to solve the equation 13 + 7x = 27?

Back

Subtract 13 from both sides to get 7x = 14.

Front

What is the second step to solve the equation 7x = 14?

Back

Divide both sides by 7 to find x = 2.

How do you solve the equation 8 = 3a - 4?

Back

Add 4 to both sides to get 12 = 3a, then divide by 3 to find a = 4.

Front

What is the solution to the equation y/3 - 7 = 1?

Back

Add 7 to both sides to get y/3 = 8, then multiply by 3 to find y = 24.

Front

What is the first step to solve the equation 4p - 3 = 17?

Back

Add 3 to both sides to get 4p = 20.

Front

What is the second step to solve the equation 4p = 20?

Back

Divide both sides by 4 to find p = 5.

Front

How do you solve the equation 1 + 2r = 35?

Back

Subtract 1 from both sides to get 2r = 34, then divide by 2 to find r = 17.

Front

What is the importance of checking your solution in a two-step equation?

Back

Checking your solution ensures that the value satisfies the original equation, confirming its correctness.
