Mathematics

7y - 4x

Step-by-step explanation:

$-3 (2x-y)+2y+2(x+y)\\$

Step 1: Open the brackets

$= -6x+3y +2y +2(x+y)\\=-6x +3y + 2y +2x + 2y$

Step 2: Bring the similar variables together

$=-6x +2x \ +3y + 2y + 2y$

Step 3: Simplify by adding/subtracting the coefficients of the similar variables

= - 4x +7y

Step 4: Rearrange as required.
