(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}

<h3>Answer:  b = 17</h3>

====================================================

Explanation:

The line must go through the point (5,2) which means x = 5 and y = 2 pair up together.

We'll plug these x and y values into the equation and solve for b.

y = -3x+b

2 = -3(5)+b

2 = -15+b

2+15 = b

17 = b

b = 17

The equation y = -3x+b turns into y = -3x+17

Ede4ka [16]
4500 + 1.20x <  4.80x
4500 <  4.80x - 1.20x
4500 <  3.60x
4500/3.60 <   x
