Answer:

$x = \frac{ - 3b}{4} \: or \: b$

Step-by-step explanation:

$\frac{1}{b + x} = \frac{3b}{2 {x}^{2} } - \frac{1}{x}$

$= > \frac{1}{b + x} = \frac{3b - 2x}{2 {x}^{2} }$

$= > 2 {x}^{2} = (b + x)(3b - 2x)$

$= > 2 {x}^{2} = 3 {b}^{2} - 2bx + 3bx - 2 {x}^{2}$

$= > 2 {b}^{2} = 3 {b}^{2} + bx - 2 {x}^{2}$

$= > 3 {b}^{2} + bx - 4 {x}^{2} = 0$

$= > 3 {b}^{2} + 4bx - 3bx - 4 {x}^{2} = 0$

$= > b(3b + 4x) - x(3b + 4x) = 0$

$= > (3b + 4x)(b - x) = 0$

Hence,

$x = \frac{ - 3b}{4} \: or \: b$

Lemur [1.5K]

Answer:

6x + 25 ≤ 135

Step-by-step explanation:

Maximum amount to spend = $135

Boxes of popcorn = 2

Boxes of candy = 3

Cost per box of popcorn = $6

For 3 boxes = $6 * 3 = $18

Cost per box of candy = $3.50

For 2 boxes = $2 * 3.50 = $7

Item cost = Cost of candy and popcorn = $18 + $7 = $25

Ticket price = $6

Inequality to find number of friends ;

Let number of friends = x

Ticket cost = 6x

Hence ;

Ticket cost + item cost ≤ 135

6x + 25 ≤ 135
