Front

Solve the expression: 3 x 9 + 7

Back

34

Front

Back

Multiply both sides by 5 to isolate x.

Front

Given the equation -9b = -14, how do you isolate b?

Back

Divide both sides by -9.

Front

Solve for y: 12 = y + 5

Back

y = 7

Front

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to multiply a single term by two or more terms inside a set of parentheses.

Front

Solve the expression: 2(4 + 9w)

Back

8 + 18w

Front

What is the solution to the equation 5x - 3 = 12?

Back

x = 3.

Front

What does it mean to isolate a variable in an equation?

Back
