drawls this is from the previous post is this correct.
solve the system by subtraction.
5x3y=13
4x3y=11
equation#2 woudl be
4x3y=11
3y = 4x+11
y = (4)/(3) x  (11)/(3)
so now i substitute it to equation #1
5x  3((4)/(3)x  (11)/(3)= 13
5x  4 x +11 = 13
1x + 11 = 13
1x = 1311
1x= 2
x = 2
now i substitute back into equation #1
5(2)3y=13
103y=13
3y = 1310
3y=3
y=1
so , my solution would be (2,1)
am i correct?
