so you need to solve it for x and y ,yes ?
jhonyy9 (jhonyy9):
so rearrange 3x +6y =9 3x +8y = 9
jhonyy9 (jhonyy9):
than you subtract second from first you will get 3x-3x +6y-8y = 9-9 ye ? can you continue ?
jhonyy9 (jhonyy9):
so will get -2y= 0 y = 0
jhonyy9 (jhonyy9):
than 3x+6*0 = 9 3x=9 x= 9/3 x = 3
