The simplified expression is 4x + 7y - 9
To simplify the expression 9x 3y - 6 - 5x 4y - 3, we can combine the like terms:
9x - 5x = (9 - 5)x = 4x
Lets Combine y terms:
3y + 4y = (3 + 4)y = 7y
Lets Combine constant terms:
-6 - 3 = -9
Lets Rewrite the expression with combined terms:
4x + 7y - 9
Therefore, the simplified expression is 4x + 7y - 9
