Arrange the equation in the "y=" format 4x - 3y = -4 -3y = -4 - 4x 3y = 4x + 4, multiplied equation by -1, y should be positive y = (4/3)x + (4/3) : Find the value of y by substituting for x: x | y -2 | -(4/3) -1 | 0 0 | +(4/3) +1 | +(8/3) +2 | +4 Plot these on a graph: x axis 4/-4 and y axis 4/-4 will work ok : Do the same with the 2nd equation: 2x-5y=-4 -5y = -4 - 2x 5y = 2x + 4 y = (2/5)x + (4/5) : Find the value of y by substituting for x: x | y -2 | 0 -1 | +(2/5) 0 | +(4/5) +1 | +(6/5) +2 | +(8/5) Plot this on the same graph, it should look like this(green is 2nd equation): : The solution is the x,y values where the lines cross. YOu can see it is not going to be an integer. I solved using elimination, got x = -(4/7) y = +(4/7) which looks about right
