Answer: The first one.
Step-by-step explanation:
Since 1.5 + 2.5 = 4, and the only graph that has an arrow pointing to 4 is the first one, then the first number line is the correct answer.
Hope this helps :)

Answer:
x = 22
Step-by-step explanation:
I interpreted your problem as:
I simplified the problem to:
I combined like terms:
I moved all x to one side and all other constants to the other:
I divided by 3/2 (1.5) on both sides to isolate x:
