Answer 1

Answer:

They are equivalent

Step-by-step explanation:

3x+6+x

2(2x + 3)

4x+6

Answer 2

Answer:

They are equivalent.

Step-by-step explanation:

Step 1 - Expand second equation:

2(2x + 3)

2(2x) + 2(3)

4x + 6

Step 2 - Simplify the first equation:

3x + 6 + x

4x + 6

Step 3 - Compare the two expressions:

4x + 6 = 4x + 6

So the two expressions are the same.

Hope this helps!
