Simplify 9b + 7x − 3b + 8x.
A 21bx
B 12b + 15x
C 6b − x
D 6b + 15x
Correct answer: D — 6b + 15x
- Collect like terms: the b terms are 9b and −3b; the x terms are 7x and 8x.
- b: 6.
- Answer: 6b + 15x.
- Why the other options are wrong:
- A (21bx): Unlike terms were combined.
- B (12b + 15x): The sign of the second x term was ignored.
- C (6b − x): The y terms were subtracted.
Only like terms can be added or subtracted: add their coefficients and keep the variable.
