Adding and subtracting general algebraic expressions

• Add 3x + 11 and 7x – 5 The sum = 3x + 11 + 7x – 5 5

• Now, we know that the terms 3x and 7x are like terms and so also are 11 and – 5.

• Further 3x + 7x = 10 x and 11 + (– 5) = 6.

• The sum = 3x + 11 + 7x – 5 

• = 3x + 7x + 11 – 5

• 10x + 6

• Hence, 3x + 11 + 7x – 5 = = 10x + 6
