Question

ache x e y sabendo que x/y=65/91 e que x + y = 136

Answer 1

$\textsf{c\'alculo~da~constante~de~proporcionalidade:}$

$\mathtt{k=\dfrac{136}{65+91}=\dfrac{136}{156}=\dfrac{34}{39}}$

$\mathtt{x=64.k=65.\dfrac{34}{39}}\\\\\huge\boxed{\boxed{\mathtt{x=\dfrac{170}{3}}}}$

$\mathtt{y=91.k=91.\dfrac{34}{39}}\\\\\huge\boxed{\boxed{\mathtt{y=\dfrac{238}{3}}}}$
