Answer:
Step-by-step explanation:
[tex]7- \sqrt[3]{2-x} =12[/tex]
we have to just keep in mind to do the same operation to both sides of the equal sign
[tex]7-7- \sqrt[3]{2-x} =12-7[/tex] ; subtract 7 from both sides
[tex]- \sqrt[3]{2-x} = 5[/tex] ; multiply both sides by -1
[tex]\sqrt[3]{2-x} = -5[/tex] ; 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
