We can replace the inequality with qual sign: 2x - y = 4 x + y = -1 We can combine both question 3x = 3 x = 1 Since we know x = 1, we can solve for y by plug in in either equation: x + y = -1 1 + y =-1 y = -2 or 2x - y = 4 2(1) - y = 4 -y = 2 y = -2
So the solution of this system of equation is the coordinate (1, -2)
