The computation of x value is shown below:-
So,
For computing the x, the following equation we need to solve which is here below:-
3 - x = 10
so x = 10 + 3
x = 13
We simply added the 3 and 10 to get the value of x
Therefore in simple words
We added the 10 with 3 to reach the x value
So the correct answer is 13
