c-2b
ok, let's see: (3a-2a) + (2b+5b) +(-c +3c) = a + 7b +2c I think that's right.
20a plus 14 will be 34a minus 8a minus 7 34a minus 8 is 26a minus 7 is 19a. The single b is 1b plus 6b which is 7b minus 2b equals 5b.
In other words: 3x+y=2z+a x+3y=2b+3a z+y=3c+a (all equals:) c+y=b+a
a^2b^2(4ab) = 8a^3b^3.
8a+2b
4a + 3c - 2b - c + a - b = 5a - 3b + 2c
c-2b
5 over 2 thats the answer
a=2b 4b=6c becomes 2b=3c a=3c
ok, let's see: (3a-2a) + (2b+5b) +(-c +3c) = a + 7b +2c I think that's right.
6abc
Assuming that non-leading numbers are exponents, the expression becomes12a^2b + 8a - 5a^2b + 2ab - 4ab^2 + 6ab - 2a - 3ab= 7a^2b + 6a + 5ab - 4ab^2= a*(7ab + 6 + 5b - 4b^2)
a + 7b + 2c
20a plus 14 will be 34a minus 8a minus 7 34a minus 8 is 26a minus 7 is 19a. The single b is 1b plus 6b which is 7b minus 2b equals 5b.
Gathering like terms together, this is equal to 5a + 3b + 7c.
6b+5a-4b+3a= ? Rearrange it as 5a+3a+6b-4b = 8a+2b
