I ned help realy bad

-3x + 4, (2,-2)

Step-by-step explanation:

First, you want to get y alone on one side.

3x + y = 4

     -4    -4        subtract 4 to get it on the left side.

     -y     -y       subtract y to get it alone on the right side.

Your'e left with 3x - 4 = -y      divide the whole equation by -1 do get a pos y

You then have y = -3x + 4. That's the first part of your answer.

To get the second part plug in (-3x + 4) into the y of the first equation, this is the substitution part.

-2x + 5(-3x+4) =-14        distribute the 5...     -2x - 15x +20 = -14

add your like terms ( x and x)                       -17x + 20 = -14

Isolate your x by subtracting the 20, both sides  -20   -20

-17x = -34    divide both side by 17 you get x = 2 ( this is your first coordinate in the pair in your answer. To get the y do the same but solve for y instead of x.

answer is:

1.75 pounds

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
