Step-by-step explanation:
You can see, MN consists of the three lines in the picture. So you just need to sum them tougher in an equation with it's original value 81.
5 + 3x - 8 + 4x = 81
7x = 81 + 3
7x = 84 / : 7
x = 12
5 parts red to 2 parts white......5:2...added = 7

white : 2/7(35) = 70/7 = 10 cans white paint
First blank is foreign then the is add then the next one is 28
