Answer 1

Answer:

Step-by-step explanation:

For number 11)

$\frac{x+3}{4} = 1$ cross multiply expressions

4 = 3+x subtract 3 from both sides

1 = x

for number 14)

$\frac{x+8}{12} = 1$ cross multiply expressions

x+8 = 12 subtract 8 from both sides

x = 4

for number 16)

$\frac{8+x}{3} = 10$ cross multiply expressions

8+x = 30 subtract 8 from both sides

x = 22

for number 19)

$\frac{-9 + b}{32} = -1$ cross multiply expressions

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

b = -22
