Answer:

[tex] \therefore [/tex] The number is 11

Step-by-step explanation:

Let x be the number. Therefore, the equation is

  • [tex] 2x - 13 = 9 [/tex]

The problem want us to know the value of the number. Therefore,

[tex] 2x - 13 = 9 [/tex]

[tex] 2x - 13 + 13 = 9 +13 [/tex]

[tex] 2x = 22 [/tex]

[tex] \frac{\cancel{2x}}{\cancel{2}} = \frac{22}{2} [/tex]

[tex] x = 11 [/tex]

[tex] \therefore [/tex] The number is 11
