Yellows 7650

Stano got a box of dice. Half of them were brown and blue in color, and the others were red, yellow, and green. There were 12 more reds than yellows, 19 more reds, and 5 more greens than yellows. How many cubes were in the box?

Correct answer:

n =  76

Step-by-step explanation:

c=19 z=c12=1912=7 z2=5+z=5+7=12  n/2 = c+z+z2 n=2 (c+z+z2)=2 (19+7+12)=76
