I need help with these:
2/3 b+ 4 = 5
a/4 - 2 = 3
1/5 z- 1 = 3
- 1/5b - 2/5 = -2
3/4 f+ 5=-5
7b +6 = 2b - 19
And what I mean is can you please solve them on a piece of paper and take a picture of it and upload it here because I wont understand it if you explain it on here. Please help I could learn this if someone solves these and I could use them as examples for everything else and I don't have these equations because I got sick and wasn't at school for like a week so please solve these on a peice of paper and upload the picture to here
 
1. (2/3) b+ 4 = 5
(2/3)b = 5-4
2b/3 = 1
2b = 3
b = 3/2
b = 1.5

thats how you solve the rest. Put like terms together
