To solve this is really simple and easy needhelp!You just have to do step by step as the question says!and as u dont know the number you will assume it to be x and just do as the question says and that will give u ur answer!Let me show you!
Here we are assuming the munber to be x so....
i think of a number = x
i add 126 = x + 126
i multiply by 19 = x + 126 * 19
the answer is 46
x + 126 * 19 = 46 (now just solve this equation and you'll get your x or in other words you can say that u'll get ur number)
x + 126 * 19 = 46
x + 2394 = 46
x=46 - 2394
x= - 2,348 ANSWER
so we've got our x which is -2,348
Now if you want me to show you the proof for the answer is correct then the proof is here
Here we have placed -2,348 in place of x as the number
-2,348 + 126 * 19
=46 ANSWER
so now uve seen that our answer is correct!
I hope now uve understood but if not then pls be free to ask!
i hope this helps!
