5.
-4n+ 7+ 2n= 1
⇒ (-4n+ 2n)+ 7= 1 (combine like terms)
⇒ -2n= 1-7
⇒ -2n= -6
⇒ n= -6/(-2)
⇒ n= 3
Final answer: B. 3~
6. 4(y-4)= 8
⇒ y-4= 8/4
⇒ y-4= 2
⇒ y= 2+4
⇒ y= 6
Final answer: D. 6~

I used phone math!!!!!!!!
2x< -9 +1
2x< -8
x< - 8/2
x< - 4
3x> 2 - 5
3x > - 3
x> -3/3
x > -1
the third is the answer
