Answer:

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
