I have forgotten how to do this question:
x + 2y = 11
3x  2y = 9

SAFFIRETWO
x+y=112
x+y=9

Chill5on
I have to solve X and Y

SAFFIRETWO
3x2y=9
xy=93+2
xy=8

Chill5on
I don't think that's how we learnt it o_0
We learnt it like,
Part 1 = To find X
x + 2y = 11
3x  2yy = 9
__________
4x = 20
 
4 = 4 = 5
x = 5

Chill5on
Then for Y =
X = 5 so...
5 + 2y = 11
3(5)  2y = 9
_________
2y = 11  5
2y = 9  15
_________
2y = 6
2y = 6
then..... I'm lost

Chill5on
Oh I got it now xD

x + 2y = 11
3x  2y = 9
4x=20 (divide by 4)
x=5 (sub 5 for x in first equation to find y)
5+2y=11
55+2y=115
2y=6(divide by 2)
y=3
Hope this helps :)

Chill5on
Thanks!! :D Definitely helped! :)
