say we have equation 1 (the first) and the second equation equation 2. let's multiply eq 1 by 3 so we have 6x-15y=3 and eq 2 by 2 so we have 6x-8y=-2

What do you get if you subtract the two newly formed equations?

-23y = 5
Sepeario
  • Sepeario
oops the second new equation is 6x-8y=-4

just check your working, you need to remember that subtracting a negative equals an addition instead.
