Respuesta :

Aliana has $42.50

if she wants to buy a sweater that cost $29

and some pairs of socks $4.50 each

in this case

x is the number of pairs of socks that Aliana can buy

so the equation is

29+4.50x=42.50

we need to clear x

4.50x=42.50-29

4.50x=13.50

x=13.50/4.50

x=3

she can buy 3 pairs of socks
