Answer:

x = -2

Step-by-step explanation:

Picture attached, shows a weighing scale in the balanced form,

So weight of elements on the left = Weight of the elements on the right

Left side of the scale = weight of x + weight of 1

                                   = x(2) + 1(6)

                                   = 2x + 6

On the right side of the scale = Weight of (-x) + weight of (-1)

                                                 = (-x)(2) + (-1)(2)

                                                 = -2x - 2

Since, both the sides are balanced,

Therefore, equation which models the situation is,

(2x + 6) = -(2x + 2)

(2x + 6) + (2x + 2) = 0

4x + 8 = 0

4x = -8

x = -2

Problem 3: Let x = price of bag of pretzels Let y = price of box of granola bars  
We have Lesley's purchase: 4x+2y=13.50
 And Landon's: 1x+5y=17.55 
 We can use the elimination method. Let's negate Landon's purchase by multiplying by -1. -1x-5y=-17.55 
 We add this four times to Lesley's purchase to eliminate the x variable.
 2y-20y=13.50-70.2
 -18y=-56.7
 y = $3.15 = Price of box of granola bars
 
 Plug back into Landon's purchase to solve for pretzels.
 x+5*3.15=17.55
 x+15.75=17.55
 x = $1.80 = price of bag of pretzels
  
 Problem 4.
 Let w = number of wood bats sold
 Let m = number of metal bats sold
 
 From sales information we have: w + m = 23
 24w+30m=606 
 Substitution works well here. Solve for w in the first equation, w = 23 - m, and plug this into the second. 
 24*(23-m)+30m=606
 552-24m+30m=606
 6m=54
 m=9 = number of metal bats sold
 Therefore since w = 23-m, w = 23-9 = 14. 14 wooden bats were sold.
