@AfreenPixel This is basic algebra. No wonder few can solve it. 8x+10=34. Subtract 10 from each side to get: 8x = 24.
Divide both sides by 8 to get x = 3. Now 3 squared = 9. The impotant thing to know is that whatever you do to one side if an = sign you MUST do exact same to the other side.
@Mimiiben1 Remeber that square root of 49 = +7 and =7. Square root of 9 = +3 and -3. Square root 4 = +2 and -2. Try all different combination to come up with the answers of 2, -2, 5, -5
@Elifbenad AรA = 100. So A = +10 or -10
A+B = 15 so B = 5 or 25
Now just substitute all combinations and you come up with
(A x B) / (A - B) = 10 or -10
