Answer: 
Step-by-step explanation:
divided by
is the same thing as multiplying
by
.
The equation we get is:

With this equation, we can factor each equation:

We can cancel out like terms since they would be dividing each other:

We can solve this by substitution method.
Look at the second equation. If we rearrange to find 7x, we can substitute in the value into the first equation.



Therefore, 
Now replace the 7x in the first equation with 5y - 12:
(substitute in 7x = 5y - 12)




Now that we know y, we can find x by substituting in y = 1 into any equation we want. I will use the equation: 7x = 5y - 12
(substitute in y = 1)
