Solve 8z − 1 = 63:
8z = 63 + 1 = 64
z = 64/8 = 8
So z = 8. None of the listed choices exactly equals 8 (the choice "88" looks like a typo), so the correct value is 8.
8z = 63 + 1 = 64
z = 64/8 = 8
So z = 8. None of the listed choices exactly equals 8 (the choice "88" looks like a typo), so the correct value is 8.
