Answer:


\boxed{x = -4~~and~~y = 0}

.

Explanation:

Use elimination

-3x + 5y = 12

7x - 5y = -28 +


4x = -16


x = (-16)/(4)


x = -4

.

Subsitute the value of x to one of equations


-3x + 5y = 12


-3(-4) + 5y = 12


12 + 5y = 12


5y = 12 - 12


5y = 0


y = (0)/(5)


y = 0

.

Happy to help :)
