If you desire please help me with this algebra grade 6 classkick please!

The input was one square so multiplied 2 would be 2 squares which is shown on both function machines. Then if you add 5 to the output you can see it because the blue part of the output is shown as a whole instead of 5 parts on the second function machine, so the value is still the same.

Step-by-step explanation:

3x-4+2x+10+3x-7+4x

12x - 1 (C)
