. . .x - y = 3

. . .3x - 2y = 3

I have tried to solve this problem but I cannot figure out what I am doing wrong. Here is what I have done so far.

. . .x - y = 3

. . .x - y - x = 3 - x

. . .y = 3 - x

. . .3x - 2y = 3

. . .3x - 2(3 - x) = 3

. . .3x - 6 + 2x = 3

. . .5x - 6 = 3

. . .5x - 6 + 6 = 3 + 6

. . .5x = 3 + 6

. . .5x = 9

. . .x = 9/5
