Question

porfa lo nesesito estoy en clase ​

Answer 1

a.

$P=3x+4y+(3x-x)+x+(4y-x)+x$

$P=3x+4y+3x-x+x+4y-x+x$

$P=6x+8y$

b.

$P=\frac{8}{3}y+2y+2y+(2y-y)+(2y-y)+(\frac{8}{3}y-\frac{2}{3}y-\frac{2}{3}y)+\frac{2}{3}y+\frac{2}{3}y$

$P=\frac{8}{3}y+2y+2y+2y-y+2y-y+\frac{8}{3}y-\frac{2}{3}y-\frac{2}{3}y+\frac{2}{3}y+\frac{2}{3}y$

$P=\frac{34}{3}y$
