Answer:
no solution
Step-by-step explanation:
x+y=7
x=3-y
Substitute the second equation into the first
(3-y) +y = 7
Combine like terms
3 = 7
This is never true so there is no solution
[tex]\boxed{\mathrm{No \: solution}}[/tex]
x + y = 7
Plug x = 3 - y
3 - y + y = 7
Combine like terms.
No solution.
