Since the opposite operation of addition is subtraction you subtract. So you add 14 both sides and now z is by itself. finally just add 2 and 14 which is 16
Hello from MrBillDoesMath!
Answer:
-6.9
Discussion:
1.3n - 0.03 = -9 => multiply both sides by 100
130n - 3 = -900 =>
130n = -900 +3 = -897 => add 3 to both sides
n = -897/130 =>
n = - (69 * 13)/ (10*13) =>
n = - 69/10 = - 6.9
Thank you,

1500-125=1,375
so 1375 should be your answer.
