Answer provided by our tutors
let
a = the weight of 1 apple
b = the weight of 1 banana
g = the weight of 1 grape
Two apples weight the same as a banana and a grape
2a = b + g
A banana weights ye same as 19 grapes
b = 19g
plug b = 19g into 2a = b + g
2a = 19g + g
2a = 20g divide both sides by 2
a = 10g
1 apple weights the same as 10 grapes.
