Answer:
[tex]4x + 11y[/tex]
Step-by-step explanation:
Step 1: Combine like terms
[tex]2x + 7y - x + 4y + 3x[/tex]
[tex](2x - x + 3x) + (7y + 4y)[/tex]
Answer: [tex]4x + 11y[/tex]
8x +11y
to solve this simply combine the varriables with the same coefficient and evaluate.
2x+7y-x+4y+3x
rearrange your varriables for accuracy
2x-x+4x +3x +7y+4y
8x + 11y
