We will solve as follows:
14x = 65 - 15y
-2(7x = -5 - 15y)
----------------------
14x = 65 -15y
-14x = 10 + 30y
----------------------
0 = 75 + 15y => 15y = -75 => y = -5
*So, we have that the value of y is -5.
Now, we replace and solve for x:
7x = -5 - 15(-5) => 7x = 70 => x = 10.
*So, the solution for the system is the point (10, -5).
