To do this you want to solve for one variable at a time. So we want to cancel out a variable. Lets cancel x. I will multiply the first equation by the number 4 to get 4y=4x-16. Now lets solve equation 2 for y, giving -3y=-4x+3 now add equation 1 to equation 2 Y =-13 Now plug that back in to either -13=x-4 X=-9 So the answer is (-9,-13)
