The ratio given for the first equation is:

b/64 = 8/32

b/64 = 1/4

b = 16

The ratio given for the second equation is:

y/4 = 7/49

y/4 = 1/7

y = 4/7

Solving the third equation:

380 - b = 330 - 175

380 - 16 = 330 - 175

364 = 155

This equation is not correct.

Solving the fourth equation:

m + 32 = 185 - 143

m + 32 = 42

m = 42 - 32

m = 10
