First, isolate x in x-4y=11 because 1 is x's coefficient. x-4y=11 x=11+4y Now, substitute 4y+11 for x in 5x-7y=-10. 5x-7y=-10 5(4y+11)-7y=-10 20y+55-7y=-10 Add all coefficients. 13y+55=-10 Isolate y by subtracting 55 from both sides. 13y+55=-10 13y=-10-55 13y=-65 y=-5 Now substitute -5 for y in your first equation. x=11+4y x=11+4(-5) x=11-20 x=-9 Your answer would be (-9,-5).
