Answer: the number of blues is 42.

the number of whites is 30.

Step-by-step explanation: Let there be 'x' blues and 'y' whites then

the ratio of blues to white is 7 to 5:

x : y = 7 : 5

the number of blues exceeds the number of whites by 12

x = 12 + y

the solutions of the system of equations

x/y = 7/5

x = 12 + y

are

x = 42 blues

y = 30 whites
