The painter

In order for the painter to get the desired color, he must mix green and yellow in a ratio of 4: 7. If it has 28 l of green color, how many liters of yellow color should he add? How many liters of mixed color does he get?

Correct result:

y =  49 l
V =  77 l


g=28 l  4:7=g:y  y=g 74=28 74=49 l
V=g+y=28+49=77 l
