#2: 
5y + 2 = 10y + 4
2 -4 = 10y-5y
5y = -2
y = -2/5

stormfire1 · Answer

#3
0.5b + 4 = 2(b + 2)
4 = 2b + 4 - .5b
0 = 2b -.5b
1.5b = 0
b = 0

stormfire1 · Answer

#4
8 – (3 + b) = b – 9
8-3-b = b - 9
8-3 = b+ b-9
5 = 2b - 9
2b=-4
b = -2

anonymous · Answer

Q4  8 – (3 + b) = b – 9
             -2b = -14
                b = 7
