$4a - 3b + c, \: 7a + 2b + 7c \\ \therefore 4a - 3b + c + 7a + 2b + 7c \\ \therefore 4a + 7a - 3b + 2b + 7c + c \\ \therefore 11a - 4b + 7c$

Explaination:-

❖ After 4a - 3b + c we have to put opposite signs according to the Rules of Algebraic Expressions.

❖ Now, Arrange them with the same alphabets at the ending and also put the sign which is inserted before a particular term.

❖ Now the last work, Play with Signs. That means, If before 3b + 2b the (-) sign is putted. Just multiply the signs and do the sum.

For example:-

❖ (-) × (+) = (-)

❖ - 3b + 2b = 4b cause, The result/answer by multiplying both the signs (-) × (+) = (-) is the answer so subtract both.

❖ And insert the signs in the last as it is. Like before 3b (-) sign is kept so, Just put (-) before 4b.

❖ Also remember, At last it's 7c + c. In such case, You’ve to write 7c as the answer.

If you don't know the multiplication of signs.

Here it is:-

❖ (-) × (-) = (+)

❖ (+) × (+) = (+)

❖ (-) × (+) = (-)

❖ (+) × (-) = (-)
