You would first develop a system of two equations in two variables.
x count pounds apples
y count pounds bananas
x+y=3.8 accounts for pounds.
1.9x+0.75y=5.84 accounts for cost.
Use the pounds equation to substitute either for x or for y, into the cost equation, simplify, and see what matches.

That's how I got it
