Solving One Step Equations

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 - 5 = 5?

Back

Add 5 to both sides: x - 5 + 5 = 5 + 5, so x = 10.

Front

What is the solution to the equation 3c = 12?

Back

Divide both sides by 3: 3c/3 = 12/3, so c = 4.

Front

How do you solve the equation 10/x = 2?

Back

Multiply both sides by x: 10 = 2x, then divide by 2: x = 5.

Front

What is the solution to the equation 8x = 32?

Back

Divide both sides by 8: 8x/8 = 32/8, so x = 4.

Front

How do you solve the equation 9 + x = 18?

Back

Subtract 9 from both sides: 9 + x - 9 = 18 - 9, so x = 9.

Front

What operation do you perform to isolate a variable in an equation?

Back

You perform the inverse operation of what is currently applied to the variable.

Front

What is the inverse operation of addition?

Back

Subtraction.

Front

What is the inverse operation of multiplication?

Back
