Answer: I dont know which to slove for so im going to put both :)
Step-by-step explanation:
SOLVING FOR Z:
Subtract 4 a from both sides of the equation.
2 z = 6 − 4 a
Divide each term by 2
and simplify. z = 3 − 2 a
SOLVING FOR A:
Subtract a from both sides of the equation
2z=6-4a
Divide each term by 2 then simplify
z=3-2a
