2
=
?
03 - 2
b= -4 and b = 0
Ob= -4
Ob= 0 and b = 4
O b= 4

Using the rise/run rule. you would get 2/6.simp. 1/3

Were is the problem

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.
