Given a fraction of the market goods, we can find the remaining fraction by subtracting the given fraction from 1.
The fraction of the goods the farmer sells that is pears will be ...
(apples +pears) = (apples) +(pears)
pears = (apples +pears) -(apples)

Answer:
6 .
4X + 2 + X = 8X +2 -3X
5X+2=5X+2
0=0
The two sides of the equation are always equal ,so 3 or any other number can be a solution for it .
7.
6X+6-3X+6= X+4
3X+12= X+4
2X= -8
X= -4
