Answer:
Step-by-step explanation:
13x+11y-3x+3y+9
10x+11y+3y+9
13x + 11y - 3x + 3y + 9
This problem consists of combining alike parts of the equation. This means 13x and - 3x go together, 11y and 3y go together, and 9 has no other alike parts.
This shows that the answer (when combining like terms) is:
10x + 14y + 9
