6x-y=-14 2x-3y=6
eqn 1 Y = 2X + 6 eqn 2 2X - Y = 2 Rearrange eqn2 to isolate Y eqn2 Y = 2X - 2 so 2X + 6 = 2X - 2 subtracting 2X from both sides we get 6 = -2 As this is impossible this set of equations can not be solved.
[ y = -2x + any other number ] is parallel to [ y = -2x + 6 ].
y=2x/6 26=2x/6 26x6=156. 156/2=78. x=78
2x + 3y = 9x = 3, y = 1 therefore 6 + 3 = 9
