Question

square root of x minus 7 end root plus 5 equals 11

Answer 1

First thing you have to do is isolate the radical on one side of the equation. Then sqaure both sides and solve

Answer 2

√(x - 7) + 5 = 11

<=> √(x - 7) = 11 - 5

<=> √(x - 7) = 6

We have this x - 7 ≥ 0 => x ≥ 7.

<=> x - 7 = 36

<=> x = 36 + 7

<=> x = 43
