Answer:
If you mean 14x - 16y + 4x - 9 + 36x + 24 then the answer would be 54x−16y+15
Explanation:
If you mean 14x - 16y + 4x - 9 + 36x + 24 then this is how you do it
Rearrange the numbers so that the like terms are next each other:
(14x + 4x + 36x) + (−16y) + (−9 + 24)
Simplify it:
(54x) + (-16y) + (15)
Remove the parentheses:
54x + - 16 + 15
Simplify it one more time:
54x - 16 + 15
And that's your answer: 54x - 16 + 15
