 -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:

[tex]\frac{8}{15}[/tex]

Step-by-step explanation:

The given expression is

[tex]-x+4y[/tex]

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.

[tex]-\frac{4}{5}+4(\frac{1}{3})[/tex]

After multiplication we get

[tex]-\frac{4}{5}+\frac{4}{3}[/tex]

Taking LCM, we get

[tex]\frac{3(-4)+5(4)}{15}[/tex]

[tex]\frac{-12+20}{15}[/tex]

[tex]\frac{8}{15}[/tex]

Therefore, the value of given expression is [tex]\frac{8}{15}[/tex].
