    We know the value of x coordinate. Do you agree ?

    Yes. 3(-1) + 2y = -2 -3 + 2y = -2 And then? How could i determine the value of y coordinate?

    -3 + 2y = -2 add +3 on both sides. What you get ?

    -3 + 2y + 3 = -2 +3 2y =1 Now divide both side by 2 we get y = 1/2 ................... Ans. Hence required coordinate is (-1, 1/2)
