Evaluate -x+4y when -x=-4/5 and y= 1/3 write your anwser as a fraction or mixed number
Bogdan [553]

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}.

vovikov84 [41]

Answer:

x = 26 , y = 33

Step-by-step explanation:

3x + 2y = 144 (1)

2x + 5y = 217 (2)

3x + 2y = 144

(divide the equation by 3)

x + (2/3)y = 48

x = 48 - (2/3)y

Plug into (2)

2[48 - (2/3)y] + 5y = 217

96 - (4/3)y + 5y = 217

11y/3 = 217 - 96

11y/3 = 121

y = 121×3/11

y = 33

x = 48 - (2/3)y

x = 48 - (2/3)(33)

x = 48 - 22

x = 26
