Step-by-step explanation:
6. 4x−1−5x+17
=4x+−1+−5x+17
Combine Like Terms:
=4x+−1+−5x+17
=(4x+−5x)+(−1+17)
=−x+16
Answer:
=−x+16
7. (−x−3)−(5x−4)
Distribute the Negative Sign:
=−x−3+−1(5x−4)
=−x+−3+−1(5x)+(−1)(−4)
=−x+−3+−5x+4
Combine Like Terms:
=−x+−3+−5x+4
=(−x+−5x)+(−3+4)
=−6x+1
Answer:
=−6x+1
8. −9x+2−(−8x−2)
Distribute the Negative Sign:
=−9x+2+−1(−8x−2)
=−9x+2+−1(−8x)+(−1)(−2)
=−9x+2+8x+2
Combine Like Terms:
=−9x+2+8x+2
=(−9x+8x)+(2+2)
=−x+4
Answer:
=−x+4
