Solving One-Step Equations add and sub

Front

What is a one-step equation?

Back

A one-step equation is an algebraic equation that can be solved in a single step by performing the same operation on both sides of the equation.

Front

How do you solve the equation x + 21 = 56?

Back

Subtract 21 from both sides: x = 56 - 21, so x = 35.

Front

What is the first step to solve w - 30 = 45?

Back

Add 30 to both sides: w = 45 + 30, so w = 75.

Front

Solve for x: x + 7 = 19.

Back

Subtract 7 from both sides: x = 19 - 7, so x = 12.

Front

What is the solution to the equation p - 5 = 13?

Back

Add 5 to both sides: p = 13 + 5, so p = 18.

Front

How do you solve the equation 20 = x - 27?

Back

Add 27 to both sides: x = 20 + 27, so x = 47.

Front

What operation do you perform to isolate x in x + a = b?

Back

Subtract a from both sides.

Front

What operation do you perform to isolate w in w - a = b?

Back

Add a to both sides.

Front

If x + 5 = 10, what is x?

Back

x = 10 - 5, so x = 5.

Front

If 30 = y - 10, what is y?

Back

y = 30 + 10, so y = 40.
