Front

What is a one-step equation?

Back

A one-step equation is an algebraic equation that can be solved in a single operation, such as addition, subtraction, multiplication, or division.

Front

How do you isolate a variable in an equation?

Back

To isolate a variable, you perform the inverse operation on both sides of the equation to get the variable by itself.

Front

Front

If x + 3 = 17, what is the value of x?

Back

x = 14.

Front

If 4 + b = 30, how do you find b?

Back

Subtract 4 from both sides: b = 30 - 4, so b = 26.

Front

What is the solution to the equation y + 51 = 99?

Back

y = 99 - 51, so y = 48.

Front

How do you solve the equation -4 - x = 6?

Back

Add 4 to both sides to get -x = 10, then multiply by -1 to find x = 10.

Front

If 2 + n = 16, what is n?

Back

n = 16 - 2, so n = 14.

Front

What is the first step in solving the equation 17 = x + 3?

Back

Subtract 3 from both sides to isolate x.
