Question

Solve graphically
3x+2y=12
5x-2y=4.
Also find the coordinates of the points where the lines meet the Y axis

Answer 1

  3x + 2y = 12                              5x - 2y = 4
 -3x           -3x                             -5x          -5x
2y = 12 - 3x                                      -2y = 4 - 5x
divide by 2 on both sides            divide by -2 on both sides
y = 6 - 3/2x                                        y = -2 + 5/2x
