Respuesta:
x=76
Explicación paso a paso:
0.08x + 0.12(266-x) = 0.38x
[tex]\frac{8x}{100} + \frac{12(266-x)}{100}=\frac{38}{100}[/tex]
[tex]\frac{8x}{100} + \frac{3192-12x}{100}=\frac{38x}{100}[/tex]
[tex]\frac{3192-4x}{100} =\frac{38x}{100}[/tex] los 100 se simplifican
[tex]3192=42x[/tex]
[tex]76=x[/tex]
