Hello, I need help solving two systems of equations. I'm not sure how to solve them. They are:

Question

7w+e=8
e+5=9

And the second one is:
7e=107-6d
7e+8d=117

Thanks!

Answer 1

#1,
from the 2nd,
e = 4
sub that into the first:
7w + 4 = 8
7w = 4
w = 4/7

I feel suspicious that this problem contained a typo

#2
just use substitution,
since 7e = 107 - 6d
in the 2nd:
107 - 6d + 8d = 117
2d = 10
d = 5
then 7e = 107 - 6(5)
7e = 77
e = 11

Answer 2

Thank you so much! Oh, and I checked and the first problem doesn't contain a typo.
