x=2

Explanation:

Step 1
In order to solve for x in the given equation, you need to isolate for x, that is, get it to one side of the equation.

Starting with,

14=9x-4

Add 4 to both sides.

14color(white)(i)color(red)(+4)=9x-4color(white)(i)color(red)(+4)

18=9x

Step 2
Now that the term with the x is on one side of the equation, you can divide both sides by 9 to determine its value.

Dividing both sides by 9,

color(red)(color(black)(18)/9)=color(red)(color(black)(9x)/9)

x=color(green)(|bar(ul(color(white)(a/a)color(black)(2)color(white)(a/a)|)))
