1.
7r – 7 = 2r + 18 (1 point)
r = –5
r = 5
r = 2.2
r = 1.2
2.
2x + 12 = 18 – x (1 point)
x = 3
x = 10
x = 6
x = 2
3.
8x – 3 = 15x + 18 (1 point)
x = –3
x = 3
x = 2.1
x = .9
4.
6y – 6 = 4y + 16 (1 point)
y = 2.2
y = –2.2
y = 11
y = 5
5.
3(x – 4) = 5(x + 2) (1 point)
x = 11
x = –11
x = 1
x = –1
What I chose
1.2
2
.9
2.2
1
If I'm wrong please explain how to do this

1.2  no
2  yes
.9  no
2.2  no
1  no
Here's how to do the first one.
7r – 7 = 2r + 18
Subtract 2r from both sides.
5r  7 = 18
Add 7 to both sides.
5r = 25
Divide both sides by 5.
r = 5
Do the others the same way. 
Thank you, Ms.Sue!
