Answer:
7x + 8y - 5
Step-by-step explanation:
Like terms are terms with the same variable as well as the same amount of said variable:
Set the expression:
4x + 3y - 4 + 5y + 3x - 1
4x + 3x + 3y + 5y - 4 - 1
Combine like terms:
(4x + 3x) + (3y + 5y) + (-4 - 1)
(7x) + (8y) + (-5)
7x + 8y - 5 is your answer.
