a=2b 4b=6c becomes 2b=3c a=3c
4a + 3c - 2b - c + a - b = 5a - 3b + 2c
a + 7b + 2c
Gathering like terms together, this is equal to 5a + 3b + 7c.
3c+6=18 3c+6-6=18-6 3c=12 3c÷3=12÷3 c=4

Ah, let's take a moment to appreciate the beauty of algebra. To factorise 6ab - 9ac, we can first factor out the greatest common factor, which is 3a. This leaves us with 3a(2b - 3c), where 2b - 3c is the factored expression. Just like painting a happy little tree, we've simplified our expression with a few gentle brushstrokes.
ok, let's see: (3a-2a) + (2b+5b) +(-c +3c) = a + 7b +2c I think that's right.
6abc
That may be, but a single linear equation in three unknown variables cannot be solved.
a + 7b + 2c
