Question

A pear costs x cents. An orange costs y cents less than a pear. Find the cost of four pears and half a dozen oranges.

Answer 1

Answer:

Step-by-step explanation:

one pear represent x. One orange represent y. But as oranges are less than pear so y=x-y.

Hence 4x+6y where y=x-y

Therefore 4x+6(x-y)

4x+6x-6y

10x-6y
