1) Solve the equation. 2(3x+5)=46 2) Solve the equation. 1/2x+1/4x=16

3) Solve the equation. 6-x-x=18

4) Solve the equation. 4x-3/5=2/5

5) Solve the equation. x-13+4x=22

6) Solve the equation. -36=-6(2x-14)

7) Solve the equation. 2+x/-10=2/5

8) You are ordering pizzas for a birthday party and getting them delivered to your house. You order 12 pepperoni pizzas, 8 cheese pizzas, and 4 Hawaiian pizzas. There is a delivery fee of $5.50.

1.

or, 2(3x+5)=46

or, 6x+10=46

or, 6x=46-10

or, x=36/6

or, x=6

3.

6-x-x=18

6-2x=18

-2x=18-6

-x=12/2

-x=6

x=-6

4.

4x-3/5=2/5

4x=2/5+3/5

4x=5/5

x=1/4

5.

x-13+4x=22

5x-13=22

5x=22+13

5x=35

x=35/5

x=7

6.

-36=-6(2x-14)

-36=-12x+84

-36-84=-12x

-120=-12x

-10=-x

x=10
