2x-3y = 13 x + 2y = -4 For this case, the first thing we can do is rewrite the system of equations as: 2x-3y = 13 -2x-4y = 8 We now add both equations obtaining: -7y = 21 We clear y: y = 21 / -7 y = -3 We substitute the valos of y = -3 in any of the equations to find x: x + 2 (-3) = - 4 We clear x: x-6 = -4 x = -4 + 6 x = 2 Answer: 2x-3y = 13 x + 2y = -4 The solution to the system of equations is: x = 2 y = -3
