Can someone break this down step by step so i know how to do it please
thankyou .

Answer 1

Answer:

12x+3y+3

Step-by-step explanation:

Let's simplify step-by-step.

4x+2y+6+7x+3y−4+x−2y+1

=4x+2y+6+7x+3y+−4+x+−2y+1

Combine Like Terms:

=4x+2y+6+7x+3y+−4+x+−2y+1

=(4x+7x+x)+(2y+3y+−2y)+(6+−4+1)

=12x+3y+3

Step 1: Define

(4x + 2y + 6) + (7x + 3y - 4) + (x - 2y + 1)

Step 2: Simplify

1. Combine like terms (x):                    12x + 2y + 6 + 3y - 4 - 2y + 1
2. Combine like terms (y):                    12x + 3y + 6 - 4 + 1
3. Combine like terms (Z):                    12x + 3y + 3
