Question
Solve the equation
z=−3
Evaluate
8z−12=12z
Move the variable to the left side
8z−12−12z=0
Subtract the terms
More Steps

Evaluate
8z−12z
Collect like terms by calculating the sum or difference of their coefficients
(8−12)z
Subtract the numbers
−4z
−4z−12=0
Move the constant to the right side
−4z=0+12
Removing 0 doesn't change the value,so remove it from the expression
−4z=12
Change the signs on both sides of the equation
4z=−12
Divide both sides
44z=4−12
Divide the numbers
z=4−12
