Question 879646
Multiply EVERY term in equation 1 by -2 to get


x + 2y = 13


-2x -4y = -26



We now have this system


-2x - 4y = -26
2x - 3y = -9



Add the equations to get



-2x - 4y = -26
2x - 3y = -9
-------------
0x - 7y = -35


So -7y = -35 which means y = 5 (divide both sides by -7)


Once you have y = 5, you use this to find x. Pick any equation with x,y in it and plug in y = 5 to solve for x. I'll let you do this part.
