Step-by-step explanation:
Since the equations will have a different slope, there must lie only one solution so the 1st two options are wrong.
Let solve using substitution
[tex]d = e + 4[/tex]
[tex]e + 4 + e= 2[/tex]
[tex]2e + 4 = 2[/tex]
[tex]e = - 1[/tex]
Plug this back in for one of the equations,
[tex]d - e = 4[/tex]
[tex]d - ( - 1) = 4[/tex]
[tex]d + 1 = 4[/tex]
[tex]d = 3[/tex]
So the solution is (3,-1).
