Answer: 5
Step-by-step explanation:
Since, According to the BODMAS, when we solve an expression,
We follow the following sequence,
1. Bracket/ parenthesis
2. Of
3. Division
4.Multiplication
5. Addition
6. Subtraction
Here, the given expression is,

Thus, solving the given expression by following the BODMAS,
We get,
Step 1. 
Step 2. 
Step 3. 
Step 4. 5
2(x+6)=x(x+1)
2x+12=x^2+x
x^2-x-12=0
(x-4)(x+3)=0
x-4=0
x=4
x+3=0
x=-3
