4/13y – 7=6
8a – 3+1.2a = 9
5f + 1/8 = 3 (Find the value of f)
p + 3/10 = 4 (Find the value of p)

4/13y7=6
4/13y=6+7
4/13y=13
4/13=13y
4/(13*13)=y
4/169=y
p+3/10=4
p+3/10=40/10
p=40/103/10
p=37/10
p=3.7
you can solve the other two in the same method, hope this helps! 
First, you want to get the numbers on one side and the terms containing the unknown on the other.
4/13y – 7 = 6
4/13y = 13
To get the y alone on one side, multiply both sides by 13/4.
y = 13(13/4)
y = 169.4 or 42.25 or 42 1/4
I hope this makes the process clearer.
