this from my algebra with trigonometry class

Answer:
a. x = 32
b. x = 55
c. y = -18
Step-by-step explanation:
a. [tex]\frac{1}{8} x=4[/tex]
Multiply both sides by 8.
[tex]8*\frac{1}{8}x =4*8[/tex]
Simplify.
x = 32
b. [tex]\frac{1}{5} x=11[/tex]
Multiply both sides by 5.
[tex]5*\frac{1}{5} =11*5[/tex]
Simplify.
x = 55
c. [tex]\frac{1}{9} y=-2[/tex]
Multiply both sides by 9.
[tex]9*\frac{1}{9} y=9(-2)[/tex]
Simplify.
y = -18
