Question

What is the solution of sqrt(x+2) -15=-3

Answer 1

`\displaystyle\\√(x+2)-15=-3\\\\√(x+2)=-3+15\\\\√(x+2)=12~~\Big|~^2\\\\x+2=144\\\\x=144-2\\\\\boxed{x=142}`

.

Answer 2

x = 142

Explanation:

We are given the following expression for which we are to find the solution:

`\sqrt { x + 2 } - 1 5 = - 3`

Rearranging the equation to get:

`\ sqrt { x + 2 } = - 3 + 1 5`

Taking square root on both sides of the equation to get:

`(√(x+2) )^2=(12)^2`

`x+2=144`

x = 142
