I will gladly simplify it.
9k - 6k + 7k - 8
9k - 6k = 3 k
3k + 7k - 8
3k + 7k= 10k
10k - 8 = 2k
So the simplified form of 9k - 6k + 7k - 8 is 2k

Do 51 and 2.5 then when you get that add 42 to your answer
Y=1/x
y=k/x
Where “k” is a constant
15/2=k/4
2k=60
k=60/2
k=30
:. 15/4=30/x
15x=120
x=120/15
:.x=8.
