What is the solution of sqrt x+2-15=-3
antiseptic1488 [7]

Answer:

Step-by-step explanation:

Without brackets, we are not exactly sure what is under the root sign. There are 3 choices.

sqrt(x) + 2 - 15 = - 3

sqrt(x + 2) - 15 = - 3

sqrt(x + 2 - 15) = - 3

I think the middle one is what you intend. If not leave a note.

sqrt(x + 2) - 15 = - 3                Add 15 to both sides.

sqrt(x + 2) - 15+15 = - 3+15     Combine

sqrt(x + 2) = 12                        Square both sides

x + 2 = 12^2                             Do the right

x + 2 = 144                               Subtract 2 from both sides.

x + 2-2 = 144-2

x = 142
