Answer:
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€
