Answer 1

Answer:

Step-by-step explanation:

$7- \sqrt[3]{2-x} =12$

we have to just keep in mind to do the same operation to both sides of the equal sign

$7-7- \sqrt[3]{2-x} =12-7$ ; subtract 7 from both sides

$- \sqrt[3]{2-x} = 5$ ; multiply both sides by -1

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

2-x = (-5)³

2-x = -125 ; subtract 2 from both sides

-x = -125-2

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

x= 127
