One step equations Add Subtract Multiply Divide

 When we solve an equation, our goal is to isolate our variable by using our inverse operations.  What does isolate mean?  What operation is the inverse of…  Addition?  Multiplication?

Addition  X + 5 = -9  X + 5 - 5 = -9 -5  X = -14  6 + X = -4  6 - 6 + X = -4 - 6  X = 2

You try!  10 = X + 3  5 + X = 9  6 = 3 + X

Answers!!!  X = 7 = 4 = 3

Equations with subtraction  X - 5 = 8  X - 5 + 5 = 8+5  X = 13  -5 + X = 6  -5 + 5 + X = 6 + 5  X = 11

You try!  X - 7 = -1  X - 4 = 66  8 = X - 2  -8 = X – 2

Answers!!!  X = 6 = 70  X = 10  X = -6

Multiplication of Equations  3X = -9 3X/3 = -9/3  X = -3  -5X = -40  -5X/-5 = -40/-5  X = 8

You try!  4X = -16  -1X = 9  6 = 5X  12X = 3

Answers!!!  X = -4  X = -9  X = 6/5  X = 1/4

Division of Equations  1/2X = 4  (2/1)1/2X = 4(2)  X = 8  -3/4X = 6  (-4/3)(-3/4)X = 6(-4/3)  X = -8

You try! 

Answers!!!  X = 27  X = -28  X = -3  X = 16
