If 7x 9y and y/z 7/5 what is the value of x/z
Web1 feb. 2024 · There are several ways to go at this. Here's one of them. Multiply the second equation by 9/9, then substitute for 9y from the first equation. (9y)/ (9z) = 7/5. (7x)/ (9z) = 7/5. Now, multiply by 9/7. x/z = (9/7) (7/5) = (9·7)/ (5·7) x/z = 9/5. Advertisement.
