Question

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.

    Answer:

    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
