Answer 1

What is the solution to this equation? 7-1^3 √2-x=12

X=5

Answer 2

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!
