Quite easy, you can use substitution
First look at the simplest row that can be solved by itself
row 2:
2strawberries +4 = 10
2 strawberries= 6
1 strawberry = 3
Row 3: Strawberry(3)+ orange=8
1 orange= 5
Rpw 4: 14= 1coconut +orange(5)
1 coconut= 9
Row 1: Coconut(9)+ watermelon+ coconut(9)= 21
2 coconut(18)= 21
1 watermelon = 3
