Answer:

x = 127

Explanation:

$7-\sqrt[3]{2-x} = 12$ , add the cube root to both sides and subtract the 12

$7-12 = \sqrt[3]{2-x}$ , combine like terms

$-5 = \sqrt[3]{2-x}$ , raise both sides to the third power

$(-5)^(3) = (\sqrt[3]{2-x} )^(3)$ , simplify

-125= 2-x , to isolate the variable subtract 2 from both sides

-125-2 =-x , combine like terms

-127=-x , multiply both sides by -1

127=x Finished!
