The given linear equation is as follows,
2x3=x+2 .
First of all, we will add 3 to both sides of the equation, as follows,
2x3+3=x+2+3 2x=x+5
Subtracting x on both sides, we get,
     2xx=x+5x x=5
So, x=5 is the solution of the linear equation 2x3=x+2 .
Thus, by definition, it is the value which satisfies the given equation.
Hence, the correct option is (3).
