Respuesta:
pera= $9
manzana=$0.75
Explicación paso a paso:
m= manzanas
p= peras
[tex] 20m + 15p = 150[/tex]
[tex]20m = 150 - 15p \\ m = \frac{150 - 15p}{20} [/tex]
[tex]( \frac{20}{1} )( \frac{150 - 15p}{20} ) + 15p = 150 \\ \frac{3000 - 300p}{20} = 150 \\ 3000 - 300p = (150)(2) \\ 3000 - 300p = 300 \\ - 300p = 300 - 3000 \\ - 300p = - 2700 \\ p = \frac{ - 2700}{ - 300} \\ p = 9[/tex]
[tex]20m + 15(9) = 150 \\ 20m + 135 = 150 \\ 20m = 150 - 135 \\ 20m = 15 \\ m = \frac{15}{20} \\ m = 0.75[/tex]
espero te sirva mi ayuda con el primer problema
