Question : 21

Total: 40

Simplify:

4(x+2)-3(x+1)

Solution:

Concept:

Expand algebraic expressions by distributing each term, then combine like terms.

Explanation:

Apply the distributive property to each bracket.

4(x+2)=4x+8

-3(x+1)=-3x-3

Subtract the second expansion from the first.

4(x+2)-3(x+1)=(4x+8)+(-3x-3)

Group like terms together.

4x-3x+8-3

Simplify each group.

x+5

The original expression simplifies to

x+5

This corresponds to Option A.

Answer:
