There is two quantities so you have to use teo variables
Let x be apples and y for grapes
Now,
5x + 9y = 57
And according to ques,
9x + 5y = 57
You have two algebric equation which you can use to solve algebrically and can easily plot graph
For that you need to put value of one algebra and record the other value
For example
For equation one if I let x = 0 then,
0 + 9y = 57
9y = 57
Y = 57 / 9 = 6.3
X=0 y= 6.3
Similary you can plot graph by taking different values and solve equation
