To simplify the expression 9x + 3y − 6 − 5x + 4y − 3, we combine like terms.
Like terms are terms that have the same variables with the same exponents.
Combining the x terms, we have:
9x - 5x = 4x
Combining the y terms, we have:
3y + 4y = 7y
Combining the constant terms, we have:
-6 - 3 = -9
Putting it all together, we have:
4x + 7y - 9
Simplify 9x + 3y − 6 − 5x + 4y −3
