Step-by-step explanation:
2x =15+5
2x =20
Divide by 2
X=10
Answer: x = 4
<u>Step-by-step explanation:</u>
= + 2
RESTRICTIONS: x + 12 ≥ 0 and x ≥ 0 → x ≥ 0 <em>(because square roots cannot be negative)</em>
=
x + 12 = x + 4 + 4
<u> -x -4 </u> <u> -x -4 </u>
8 = 4
<u> ÷4 </u> <u>÷4 </u>
2 =
(2)² =
+/- 4 = x
Solutions: x = 4, x = -4 <em>however, x = -4 is restricted so not valid</em>
