Four oranges and five apples cost $3.56. Three oranges and four apples cost $2.76. Find the cost of an orange and the cost of an apple.

Let number of oranges be x
And number of apples be y

4x+5y= 3.56   ----------------------1
3x+4y=2.76-------------------------2

Multiply eq 1 by 3 and eq 2 by 4

12x+15y= 10.68
12x + 16y= 11.04

Subtract

-y= - 0.36 
Y=0.36
X= 0.44  give answer in appropriate units
