Question

What is the solution of StartRoot x + 2 EndRoot minus 15 = negative 3?

Answer 1

Answer:

x = 142

Step-by-step explanation:

The problem;

$\sqrt{x+2} - 15 = -3$

Inverse operations;

$\sqrt{x+2} -15 = -3\\ +15 +15\\\\\\\\\sqrt{x+2} = 12$

Now undo the square, by squaring both sides;

$\sqrt{x+2} = 12\\.^{2} \\\\\\ \\x+2 = 144$

Inverse oeprations;

x + 2 = 144

  -2        -2

x = 142
