Respuesta :

SINAZEUS
you can find the answers by thes two systems of equation
(x is number of textbooks and y is number of notebooks)
[tex]12x + 8y = 42 \\ 1x + 10y = 17.5 \\ or \\ 12x + 8y = 42 \\ 13x + 18y = 59.5[/tex]

so the answers are
[tex] \\ x = \frac{5}{2 } \\ \\ y = \frac{3}{2} \\ [/tex]





good luck
