Simplify the expression |
|
2 |
Step |
After eleminating the brackets we get |
\$ 6/7a - 7/3b + 6/4c - 9/7a - 6/3b + 2/3c \$ |
3 |
Step |
Adding like terms together |
\$ (6/7a-9/7a) + (-7/3b - 6/3b) + (6/4c + 2/3c) \$ |
4 |
Step |
Taking variables common |
\$ (6/7-9/7) a + (-7/3 - 6/3) b + (\cancel6^3/\cancel4^2 + 2/3) c \$ |
5 |
Step |
Taking LCM |
\$((6-9)/7)a + ((-7 - 6)/3)b + (3/2 + 2/3)c \$ |
6 |
Step |
After simplification we get |
\$-3/7a - 13/3b + ((9+4))/6c\$ |
7 |
Step |
After simplification we get |
\$ -3/7a - 13/3b + 13/6c \$ |
