Question

How to solve:

-8 + square root of (5a-5) = -3

Answer 1

`a=6`

Explanation:

`-8+√((5a-5))=-3`

Adding 8 both sides.

`8-8+√((5a-5))=-3+8`

`√((5a-5))=5`

Squaring both sides.

`(√((5a-5)))^2=5^2`

`5a-5=25`

Adding 5 both side.

`5a-5+5=25+5`

`5a=30`

Dividing by 5 both sides.

`(5a)/(5)=(30)/(5)`

∴
`a=6`
