Question 922392
X+2y=10 3x-y=9

Thank you,

I tried

2y=x+10 ****** 2y = -x + 10  

y=-1\2 x10  ***** Not sure what this means, but y = -x/2 + 5

3x-(1\5x15)=9
3x+1\3x-5=9
3.5x-5=9
(3,14)
===============
X+2y=10 
3x-y=9
Don't make any fractions.
3x-y=9 --> y = 3x - 9
Sub for y in the 1st eqn
--
x + 2y = 10
x + 2(3x-9) = 10
x + 6x-18 = 10
7x = 28
x = 4
