Question

Is the answer to this question 1.7692.

Answer 1

Well, since 9q + 4q = 13q, and 13q - 3 = 20, then that means that 13q would equal 23.

In short, your answer would just be $\frac{23}{13}$

But, if you were using decimal form, yours would be pretty accurate, though the more accurate answer would be 1.76923076923

Answer 2

9q + 4q = 13q
20 - 3 = 17
13q - 17 I believe is the answer
