Answer:
z = (92/a) - t is your answer
Explanation:
Isolate the z. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, combine like terms
45 + 47 = 92
First, divide a from both sides
(a(t + z))/a = (92)/a
t + z = 92/a
Isolate the z. Subtract t from both sides
t (-t) + z = (92/a) - t
z = (92/a) - t is your answer
