Answer: x = -1

Calculation/Explanation:

11x-3 = x-13
11x-3 -x = x-13 -x
10x-3 = -13
10x-3 +3 = -13 +3
10x = -10
10x /10 = -10/10
x = -1

Answer:


-1.

Explanation:

Let x be our required number.

11 times the number would be
11x.

Three less than 11 times a number would be
11x-3.

The number decreased by 13 be
x-13.

We have been given that three less than 11 times a number is the same as the number decreased by 13. We can represent this information in an equation as:


11x-3=x-13


11x-3+3=x-13+3


11x=x-10


11x-x=x-x-10


10x=-10


(10x)/(10)=(-10)/(10)


x=-1

Therefore,our required number would be
-1.
