The given equation is
[tex]17.95x+24=18.95x+18[/tex]Let's solve for x. First, we subtract 17.95x from each side
[tex]\begin{gathered} 17.95x-17.95x+24=18.95x-17.95x+18 \\ 24=x+18 \end{gathered}[/tex]Then, we subtract 18 from each side
[tex]\begin{gathered} 24-18=x+18-18 \\ x=6 \end{gathered}[/tex]As you can observe, the equation has only one solution, which is x = 6. This means they will pay the same amount of money if they buy 6 pairs of pants, not any number but 6.
