Question

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

Answer 1

Answer:

x = 127

Step-by-step 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!
