To solve these equations for y and x, we need to isolate y in the first equation and x in the second equation.

1) 4 7/12 - y = 2 5/1
First, change the mixed numbers to improper fractions:
4 7/12 = (12*4 + 7)/12 = 48 + 7 / 12 = 55/12
2 5/1 = 2 + 5 = 7
Now, solve for y:
55/12 - y = 7

2) x - 3.2 = 2 7/15
Convert the mixed number and decimal to fractions:
3.2 = 3 1/5 = 16/5
2 7/15 = 2 + 7/15 = 30/15 + 7/15 = 37/15
Now, solve for x:
x - 16/5 = 37/15
x = 37/15 + 16/5
x = 37/15 + 48/15
x = 85/15
x = 17/3

Therefore, the solutions for y and x are:
y = -29/12
x = 17/3
