Answer:

6

Step-by-step explanation:

So we have a number (let's call it x) and it was multiplied by 8 and added by 2. Therefore:

[tex]8x+2[/tex]

And we are told that the sum is equal to the product of 2 and 25 (or 50). Thus:

[tex]8x+2=50[/tex]

To find the number, we just need to find x. Thus, subtract 2 from both sides:

[tex]8x=48[/tex]

Divide both sides by 8:

[tex]x=6[/tex]

And we're done!

So, our original number was 6.
