Step-by-step explanation:
u didn't write the question, but u probably want how much did the apple cost and banana cost.
[tex]3a + 5b = 7.5 \\ 2a + 7b = 6 \\ a = 3 - 3.5b \\ 3(3 - 3.5b) + 5b = 7.5 \\ 9 - 10.5b + 5b = 7.5 \\ - 5.5b = - 1.5 \\ b = \frac{3}{11} = 0.2727.....[/tex]
[tex]a = 3 - 3.5 \frac{3}{11} \\ a = \frac{45}{22} = 2.045... \\ apple = 2.045 \\ banana = 0.27[/tex]
