Question
Simplify:
- 3(a + b) + 4(2a - 3b) - (2a - b)
- 3(a + b) + 4(2a - 3b) - (2a - b)
✓
Answer
We have:
-3(a + b) + 4(2a - 3b) - (2a - b)
= -3a - 3b + 8a - 12b - 2a + b
= -3a + 8a - 2a - 3b - 12b + b
= ( -3 + 8 - 2)a + ( -3 - 12 + 1)b
= 3a - 14b
-3(a + b) + 4(2a - 3b) - (2a - b)
= -3a - 3b + 8a - 12b - 2a + b
= -3a + 8a - 2a - 3b - 12b + b
= ( -3 + 8 - 2)a + ( -3 - 12 + 1)b
= 3a - 14b
