One-Step Equations

4x=28

divide both sides by 4

x=7

2y=156

divide both sides by 2

x= 78

Distributive Property

4(2x+5)=7(3x+2)

8x+20=21x+14

8x=21x-6

-13x=-6

x=-6/-13

x=.462

Equations Containing Fractions

y/2-5y/6=1/15

Multiply both sides by 30

15y-5(5y)=2

15y-25y=2

-10y=2

y=2/-10

y=-0.2

Equations Containing Fractions

x/2-x/3=15

Multiply all number by 6

3x-2x=90

x=90

Equation with a Decimal

4.6x+5=7

-5    -5

4.6x=2

x=2/4.6

x=.435
