Answer 2

  18
 -------  = 9
7х-28
 
9*(7х-28)=18
63х-252=18
63х=18+252
63х=270
х=270:63
х=270/63
х=30/7
х=4 2/7

Answer 3

It seems like you have an equation with a missing operator or variable in place of the blank. To solve this equation for the variable x, we need to fill in the blank with the appropriate operator. Here's how the equation could look depending on what you intended:

1. If you want to solve for x and the equation should be linear:

   18 = 97(x - 4)

2. If you want to solve for x and the equation should be a quadratic equation:

   18x^2 = 97(x - 4)

Please specify whether you meant it to be linear or quadratic, and if there's a missing operator, let me know what operator you intended to use.
