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)

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)

i think it is c hope that
