Question

1. 7r – 7 = 2r + 18

r = –5
r = 5
r = 2.2
r = 1.2

2. 2x + 12 = 18 – x

x = 3
x = 10
x = 6
x = 2

3. 8x – 3 = 15x + 18

x = –3
x = 3
x = 2.1
x = .9

4. 6y – 6 = 4y + 16

y = 2.2
y = –2.2
y = 11
y = 5

5. 3(x – 4) = 5(x + 2)

x = 11
x = –11
x = 1
x = –1

Answer 1

Intrustions: Solve the equation. Round to the nearest tenth if necessary.

Answer 2

Steve anyone help

Answer 3

these are all basically the same. Here's #5. It should help you on the others:

3(x-4) = 5(x-2)
expand to remove parentheses:
3x-12 = 5x+10

collect the x stuff on one side:
-2x = 22

divide by the coefficient of x: -2
x = -11

finally, check your answer!
3(-11-4) = 5(-11+2)
3(-15) = 5(-9)
-45 = -45

if you get stuck on the others, come on back and show how far you got.
