Question

elimination -x + 5y = 133x + 5y = 27

Answer 1

- x + 5y = 133
x + 5y = 27
----------------
10y = 160
y = 160/10
y = 16

now sub 16 in for y in either of the original equations...
x + 5y = 27
x + 5(16) = 27
x + 80 = 27
x = 27 - 80
x = - 53

check...
-x + 5y = 133
- (-53) + 5(16) = 133
53 + 80 = 133
133 = 133 (correct)

x = - 53, y = 16 ---->(53,16)

Do you have any questions about the problem I just did ?
