Question

Solve the literal equation of the given variable

(picture is included below)

Answer 1

10) y = 2x + 7

11) x =
`(y)/(7z)`

Explanation:

To solve the literal equation, you need to isolate the variable you are solving for.

10)

x =
`(y-7)/(2)`

multiply by 2:

2x = y - 7

add 7:

2x + 7 = y

y = 2x + 7

11)

y = 7xz

divide by 7:

`(y)/(7)` = xz

divide by z:

`(y)/(7z)` = x

x =
`(y)/(7z)`
