Solve the literal equation of the given variable
(picture is included below)

Answer:
10) y = 2x + 7
11) x = [tex]\frac{y}{7z}[/tex]
Step-by-step explanation:
To solve the literal equation, you need to isolate the variable you are solving for.
10)
x = [tex]\frac{y-7}{2}[/tex]
multiply by 2:
2x = y - 7
add 7:
2x + 7 = y
y = 2x + 7
11)
y = 7xz
divide by 7:
[tex]\frac{y}{7}[/tex] = xz
divide by z:
[tex]\frac{y}{7z}[/tex] = x
x = [tex]\frac{y}{7z}[/tex]
