Solving One-Step Equations by Adding or Subtracting

Front

What is a one-step equation?

Back

A one-step equation is an algebraic equation that can be solved in a single operation, either by adding or subtracting a number from both sides.

Front

How do you isolate a variable in an equation?

Back

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

Front

What is the inverse operation of subtraction?

Back

The inverse operation of subtraction is addition.

Front

Solve for x: x - 12 = -24

Back

x = -12

Front

Solve for x: x + 22 = 64

Back

x = 42

Front

Solve for x: x + 8 = 10

Back

x = 2

Front

Solve for x: x - 62 = 123

Back

x = 185

Front

What do you do to both sides of the equation to maintain equality?

Back

You perform the same operation (addition or subtraction) to both sides of the equation.

Front

If x + a = b, how do you solve for x?

Back

Subtract a from both sides: x = b - a.

Front

What is the first step to solve x - 5 = 10?

Back

Add 5 to both sides: x = 15.
