-1/8d -4 = -3/8
multiply by 8
-d -32 = -3
add 32 to each side
-d=29
divide by -1
d=-29
-1/4 m + 5 =16
subtract 5 from each side
-1/4 m = 11
multiply by -4
m = -44
10b +-45 = -43
add 45 to each side
10b =2
divide by 10
b = 2/10
b = 1/5
-8(y-1.25) = 4
divide by -8
y - 1.25 = -4/8
y -1.25 = -.5
add 1.25 to each side
y = .75
3.2(s+10) = 32
divide by 3.2
s+10 = 32/3.2
s+10 =10
subtract 10 from each side
s=0
