How To Solve Simultaneous Equations Graphically 8 Steps
Xy=4,2xy=2 To solve a pair of equations using substitution, first solve one of the equations for one of the variables Then substitute the result for that variable in the other equation xy=4 Choose one of the equations and solve it for x by isolating x2xy=4, y=2x4, y=2x4 (red line) 4x2y=8, 2y=4x8, y= (4x/2) (8/2), y=2x4 (green line) (graph 300x0 pixels, x from 6 to 5, y
