Answer:
x=4,y=9
Explanation:
We want to solve the equation:


simultaneously.
Multiply the top equation by 3 and the bottom equation by 2 to get:
6y-15x=-6
6y+4x=70
Subtract the top equation from the bottom equation.




We substitute x=4 into 2y-5x=-2 to get:



Therefore the solution to the system is
(4,9)
