Question

32:b=64:8
y:4=49:7
380-b=330-175
m+32=185-143

Answer 1

32:b = 64:8

64:8 = 8

32:8 = 4

b = 4

y:4=49:7

49:7 = 7

7*4=28

y = 28

380-b=330-175

330-175=155

380-155=225

b = 225

m+32=183-143

183-143=40

40-32=8

m = 8

Answer 2

Вот:
32:6=64:8
32:6=8
6=32:8
6=4

У:4=49:7
У:4=7
У=7*4
У=28

380-b=330-175
380-b=155
b=380*155
b=225

m+32=185-143
m+32=42
m=42-32
m=10
