What is the solution to the equation?

√x+10 - 9 = - 7

I think it is - 6 but I'm not sure

Let's solve your equation step-by-step. √x + 10 - 9 = - 7

√x + 1 = - 7

Step 1: Add - 1 to both sides.

√x + 1 + - 1 = - 7 + - 1

√x = - 8

Step 2: Solve Square Root.

√x = - 8

x = (-8) 2 (Square both sides)

x=64
