Simplify the following expression: a + 2c - 5b - c + a - b

Solution:

Given, a + 2c - 5b - c + a - b

We have to simplify the expression

Grouping the like terms,

= a + a - 5b - b + 2c - c

= 2a - 6b + c

Therefore, the simplified expression is 2a - 6b + c.

Example:

Simplify the following expression: 2a + c - 6b - 5c + 3a - 4b

Solution:

Given, 2a + c - 6b - 5c + 3a - 4b

We have to simplify the expression

Grouping of common terms,

= 2a + 3a - 6b - 4b + c - 5c

= 5a - 10b - 4c

Therefore, the simplified expression is 5a - 10b - 4c.

Simplify the following expression: a + 2c - 5b - c + a - b

Summary:

The simplified form of the expression a + 2c - 5b - c + a - b is 2a - 6b + c.
