To simplify the expression 9x + 3y - 6 - 5x + 4y - 3, we can combine like terms.
Combining the x terms, we have:
(9x - 5x) = 4x
Combining the y terms, we have:
(3y + 4y) = 7y
Combining the constants, we have:
(-6 - 3) = -9
Putting it all together, the simplified expression is:
4x + 7y - 9
simplift 9x+3y-6-5x+4y-3
