This requires inverse operations to solve. x/4 - 8 = 12 + 8 + 8 x/4 = 20 Now, we multiply by 4, because x is being divided by 4. 4(x/4) = 20(4) So, x = 80.
4 x − 8 = 12 x − 32 = 48 x = 80
To solve for x , isolate the variable in the equation by performing inverse operations. For example, in the equation x + 5 = 12 , subtracting 5 from both sides gives x = 7 . Always remember to verify your answer by substituting it back into the original equation.
