- m-6=3(k-6)
m-6=3k-18
3k-m=12. m+6=9/7 (k+6)
7m+42=9k+54
7m-9k=12, m=12, k=8 - 10 years agoHelpfull: Yes(3) No(0)

- 10 years agoHelpfull: Yes(2) No(2)
- (m-6) = 3(k-6)
3k-m = 12
m = 9/7
k = 7
m = 9 - 10 years agoHelpfull: Yes(0) No(4)
- m=4k-18
m+6-k+6=9/7(k+6)
(3k-18+6)*7=9k+54
21k-12=9k+54
12k=66
k=6
m=
