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!
