Question

Evaluate -x+4y when -x=-4/5 and y= 1/3 write your anwser as a fraction or mixed number

Answer 1

 -x+4y when -x=-4/5 and y= 1/3
= -4/5 + 4(1/3)
= -4/5 + 4/3
= -12/15 + 20/15
= 8/15

answer
8/15

Answer 2

Answer:

$\frac{8}{15}$

Step-by-step explanation:

The given expression is

$-x+4y$

We have to find the value of given expression when -x=-4/5 and y= 1/3.

Substitute -x=-4/5 and y= 1/3 in the above expression, to find the value of given expression when -x=-4/5 and y= 1/3.

$-\frac{4}{5}+4(\frac{1}{3})$

After multiplication we get

$-\frac{4}{5}+\frac{4}{3}$

Taking LCM, we get

$\frac{3(-4)+5(4)}{15}$

$\frac{-12+20}{15}$

$\frac{8}{15}$

Therefore, the value of given expression is $\frac{8}{15}$.
