María ha comprado un frasco de colonia que costaba 23 € y tres pares de medias. Le ha dado a la dependienta los 52 € que llevaba y ha dejado a deber 13 €. ¿Cuánto cuesta un par de medias en esa tienda?

the price of the socks is 22€

Step-by-step explanation:

To find the value of a pair of socks you first write an algebraic expression for the situation of the problem.

Maria has 52€, she spent 23€ and also she spent in buying the three pairs of socks. You can chose x as the price of one pair of socks, then, Maria spent 3x. In the end Maria is owd 23€.

If you subtract 23€  and 3x to 52€  you obtain a negative value of -13€ . That is:

53 - 3x = -13    (1)

From the last equation you obtain x:

- 3x = - 13 - 53

-3x = - 66

x = (66/3) = 22

hence, the price of the socks is 22€
