Question

Solve for all possible values of x.
√x-8-3=1
Ox= -4
O x = 8
O x = 12
Ox= 24​

Answer 1

Answer:

x = 24

Step-by-step explanation:

$\sqrt{x - 8} - 3 = 1 \\ \sqrt{x - 8} = 1 + 3 \\ \sqrt{x - 8} = 4 \\ squaring \: both \: sides \: \\ {( \sqrt{x - 8)} }^{2} = {4}^{2} \\ x - 8 = 16 \\ x = 16 + 8 \\ \huge \red{ \boxed{x = 24}}$
