Answer:
1. 8(b+1) = -3(2+b)
Opening brackets,
8b + 8 = - 6 - 3b
11b = -14
b = -14/11
2. -3z - 1 = 1 - 7z
4z = 2
z = 2/4 = 1/2
3. w - 5 = 8w + 5
7w = - 10
w = -10/7
4. -5f - 8 = 2(3f + 2)
Opening brackets,
-5f - 8 = 6f + 4
11f = -12
f = -12/11
5. 6g + 5 = -2(1+2g)
Opening brackets,
6g + 5 = -2 - 4g
10g = -7
g = -7/10
6. 5r = -3(r+3) - 7
Opening brackets,
5r = -3r -9 - 7
8r = -16
r = -16/8 = -2
7. -7q + 8 = -8 + 3q
10q = 16
q = 16/10 = 8/5
8. -4p - 2 = 6p + 1
10p = -3
p = -3/10
Hope it helps..!! ^_^
