Solve the system of equations using substitution. Show your work.

d + e = 6

d - e = 4

the solution is (1, 5)

Step-by-step explanation:

If d - e = 4, then d = e + 4. Substitute e + 4 for d in the first equation:

d + e = 6 → e + 4 + e = 6. Then 2e = 2, and e = 1.

Subbing 1 for e in the second equation, we get d + e = 6, or d + 1 = 6.

Thus, d = 5, and the solution is (1, 5)

d+e = 6 d=5 and e=1

d-e=4

Step-by-step explanation:

5+1=6

5-1=4
