3(1/2)+y = -8
Okay, so half of 3 is 1.5.
Then the equation is 1.5+y=-8.
Now you subtract -8 by 1.5.
You should get -9.5, and I believe that is correct. You can check the answer by replacing y with -9.5.
7(x - 3) = 4(x + 5)
7(x) - 7(3) = 4(x) + 4(5)
7x - 21 = 4x + 20
- 4x - 4x
3x - 21 = 20
+ 21 + 21
3x = 41
3 3
x = 13²/₃
9(x - 2) = 18
9(x) - 9(2) = 18
9x - 18 = 18
+ 18 + 18
9x = 36
9 9
x = 4
17x - 6 + 3x - 5 = x + 11 + 4x
17x + 3x - 6 - 5 = x + 4x + 11
21x - 11 = 5x + 11
- 5x - 5x
16x - 11 = 11
+ 11 + 11
16x = 22
16 16
x = 1³/₈
-9*2 or 36/-2 would get you the same answer as your aforementioned question. XD
JK. It's -18
