The answer is:

x=2a+b

Answer:

[tex]2(a+b)[/tex].

Step-by-step explanation:

We re asked to write an algebraic expression for the given word phrase.

The sum of 'a' and 'b' would be 'a' added to 'b' as: [tex]a+b[/tex].

2 times the sum of 'a' and 'b' would be 2 multiplied to the sum of 'a' and 'b': [tex]2(a+b)[/tex].

Therefore, our required expression would be [tex]2(a+b)[/tex].
