Step-by-step explanation:

The required expression -7b-3c+13.

Step-by-step explanation:

We need to subtract the sum of 2a + 3b, a - 2b + c, - a + 2c and 4a + 2b - 5 from 6a - 4b + 8.

Sum of 2a + 3b, a - 2b + c, - a + 2c and 4a + 2b - 5 is

Combine like terms.

Subtract 6a+3b+3c-5 from 6a - 4b + 8.

On combining like terms we get

Therefore, the required expression -7b-3c+13
