Respuesta :

Answer: The number was 9.

Step-by-step explanation:

Let the number be 'x;.

think of a number, multiply it by five and subtract three from the result :

According to Ashton, the expression would be :

[tex]5x-3[/tex]

Kamir tells Andrew to think of a number, add five and multiply the result by three:

According to Kamir, the expression would be :

[tex]3(x+5)[/tex]

At last, they get the same number :

[tex]5x-3=3(x+5)\\\\5x-3=3x+15\\\\5x-3x=15+3\\\\2x=18\\\\x=\dfrac{18}{2}\\\\x=9[/tex]

Hence, the number was 9.
