(xy+4y)/x = (3x-2)/x
(y+4y)/x = (3x-2)/x divide both side by x
5y /x = (3x-2)/x
5y= 3x-2 Mult by x both side
y= (3x-2)/5

Basically, solve for y

first undsitribute y
y(x+4)=3x-2
divide both sides by x+4
y=\frac{3x-2}{x+4}

What is the solution to this equation 5x -8(x + 5)= 6-3x
Solnce55 [7]

Answer:

no solution

Step-by-step explanation:

5x - 8(x + 5) = 6 - 3x

Remember to follow PEMDAS. Note the equal sign, what you do to one side, you do to the other.

First, distribute -8 to all terms within the parenthesis

-8(x + 5) = (-8)(x) + (-8)(5) = -8x - 40

5x - 8x - 40 = 6 - 3x

Isolate the variable (x). Add 3x & 40 to both sides

5x - 8x (+3x) - 40 (+40) = 6 (+40) - 3x (+3x)

5x - 8x + 3x = 6 + 40

Simplify. Combine like terms

(5x - 8x + 3x) = (6 + 40)

0 = 46 ; False 0 ≠ 46 ∴ no solution is your answer

How do you find the slope of a line perpendicular to a given line?
enyata [817]
You have a line:
y=mx+b  (slope-intercepted form)
m=slope of this line.

The slope of a line perpendicular to that given line will be: ´"m´"
m´=-1/m.

For example:
y=8x+3
m=8

The solpe fo a line perpendicular to "y=8x+3" is:
m`=-1/8
