Multiplying x+6y=-3 with 2 so its equal to first eqn,
Eliminating,
2x + 3y = 3 (1)
2x +12y = -6 (2) (because subtracting)
------------------
-9y =9
∴y=-1
eq. y in 1
2x -3=3
2x=3+3
x=6/2
=3

M’lea should answer 21 answers correctly out of 30 questions, because the ratio is 3/10 if you multiply by 3 on 3/10 you get 9/30 which means she gets 9 answers wrong so you subtract the 9 to 30 and you get 21
The answer is 21
