The answer to your question is letter A
Step-by-step explanation:
Expression
- 3x - (x - 1) + 3/2(3x + 3)
1.- Expand
- 3x - x + 1 + 3/2(3x) + 3/2(3)
2.- Simplify
- 3x - x + 1 + 9/2 x + 9/2
3.- Associate like terms
(-3x - x + 9/2x) + (1 + 9/2)
4.- Simplify like terms
(-4x + 9/2x) + (2 + 9)/2
(-8x + 9x)/2 + 11/2
1/2x + 11/2
