For this case, the first thing we must do is define a variable:
 x: unknown number
 We then have the following equation:
 [tex]9-6 = x [/tex]
 We are going to rewrite the equation as an addition equation.
 To do this, we add 6 on both sides of the equation:
 [tex]9-6 + 6 = x + 6 [/tex]
 Let's rewrite the left side of the equation:
 [tex]9 + 0 = x + 6 9 = x + 6[/tex]
 Answer:
 an addition equation that can help you find 9-6 is:
 [tex]9 = x + 6[/tex]
