Back

A one-step equation is an equation that can be solved in one operation, either by adding, subtracting, multiplying, or dividing.

Front

How do you solve the equation t - 7 = 11?

Back

Add 7 to both sides: t = 11 + 7, so t = 18.

Front

What is the solution to the equation g - 56 = 12?

Back

Add 56 to both sides: g = 12 + 56, so g = 68.

Front

How do you solve n + 6 = 16?

Back

Subtract 6 from both sides: n = 16 - 6, so n = 10.

Front

What is the solution to the equation x + 1.6 = 0.8?

Back

Subtract 1.6 from both sides: x = 0.8 - 1.6, so x = -0.8.

Front

How do you solve the equation q + 10 = 22?

Back

Subtract 10 from both sides: q = 22 - 10, so q = 12.

Front

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

Back

Isolating a variable means to get the variable alone on one side of the equation to find its value.

Front

What operation would you use to solve the equation x - 5 = 3?

Back

You would add 5 to both sides to solve for x.

Front

If you have the equation y + 4 = 10, what is y?

Back

Subtract 4 from both sides: y = 10 - 4, so y = 6.

Front

What is the first step to solve the equation z - 9 = 2?

Back

Add 9 to both sides to isolate z.
