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

Step-by-step explanation:

The given expression is

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.

After multiplication we get

Taking LCM, we get

Therefore, the value of given expression is .
