-2x + 3y = 13 -3(x + y = 11) take the whole bottom equation and multiply by -3 to eliminate the 3y -2x + 3y = 13 -3x -3y = -33 cancel out 3y -2x = 13 -3x = -33 add -2 to -3 and 13 to -33 to get -5x = -20 divide -5 on both sides x = 4 then you can do the exact same steps to find the y coordinates, but if x is 4 then the coordinate point is (4,7)
