Question 3
Rearrange the formula 5√x + y = z to make x the subject

Answer 1

x =
`((z-y)/(5)) ^(2)`

Explanation:

5
`√(x)` + y = z ( subtract y from both sides )

5
`√(x)` = z - y ( divide both sides by 5 )

`√(x)` =
`(z-y)/(5)` ( square both sides to clear the radical )

(
`√(x)` )² =
`((z-y)/(5)) ^(2)`

x =
`((z-y)/(5)) ^(2)`
