Solving One Step Equations Using Addition or Subtraction With Rational Numbers

Solve for x.

12.67 + x = 83.9

• x=71.23

• 71.23

• x = 96.57

• x = - 96.57

Solve  x + 2.3 = 3.07

• 5.37

• 0.77

• 7.061

• 1.33

Using the "opposite operation" to "undo" and isolate the variable when solving an equation is more commonly called...

• Inverse operations

• math

• variable

• PEMDAS

What is a 1-step problem?

• A problem where multiple operations are present.

• A problem where the variable is missing.

• An equation where only one step is needed to solve it.

• An equation where two steps are needed to solve it.

Solve.

To solve the equation
x + 5 = 8
 I would ....

• subtract 5 from x

• subtract 5 from both sides

• subtract 5 from one side and add 5 to the other

• add 5 to both sides

What is the inverse operation that must be done to both sides of the equation?
x - 17 = 17

• subtract 17 from both sides

• multiply both sides by 17

• add 17 to both sides

• divide both sides by 17

62 + j = 74

• -12

• 136

• 12

• 8

2.3 = p + 0.6

• p = -2.9

• p = 1.7

• p = 2.9

• p = 17

m - 3 = 13.8

• m = 10.8

• m = 16.8

• m = 13.5

• m = 141
