Answer:

Explanation:

For number 11)


(x+3)/(4) = 1 cross multiply expressions

4 = 3+x subtract 3 from both sides

1 = x

for number 14)


(x+8)/(12) = 1 cross multiply expressions

x+8 = 12 subtract 8 from both sides

x = 4

for number 16)


(8+x)/(3) = 10 cross multiply expressions

8+x = 30 subtract 8 from both sides

x = 22

for number 19)


(-9 + b)/(32) = -1 cross multiply expressions

-9 + b = -31 add 9 to both sides

b = -22
