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. If your total comes to $184.54, how much was each pizza? Assume that all types of pizza cost the same amount.
please help. it would honestly mean the world to me. :)))
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
