x + 5y = 15
5y = 15 - x
y = 3 - 1/5x

x+5y = 15
5y = 15-x
y = 15/5-x/5
y = 3-x/5

x + 5y = 15
Transpose x
x + 5y - x = - x + 15
5y = - x + 15
Divide both sides of the equation by 5
5y / 5 = - x / 5 + 15 / 5
y = - 1/5x + 3
- - - - - - - -s-

easy 15divided by5=3 so now you have this
x+y=3 oh shoot now im stuck.
Added:
you could do resoning with this but it wouldn't be guarenteed. Just picka nother answer im dumb. By the way reasoning would be:
1+2
2+1
0+3
3+0
and then you get negatives number like:
-1+4
actually thatwould be all equal to 3 so yeah.
