Simplify by combining like terms: 5a − 8c + b + 3c −9a + 6b the answer i got was -4a+7b-5c am i correct?
Yes, you are correct. The simplified expression is: -4a + 7b - 5c.
Yes, your answer is correct. To simplify the given expression by combining like terms, we group the variables with the same coefficients:
5a − 8c + b + 3c − 9a + 6b
Combine the "a" terms: 5a − 9a = -4a
Combine the "c" terms: -8c + 3c = -5c
Combine the "b" terms: b + 6b = 7b
Therefore, the simplified expression is -4a + 7b - 5c, which matches the answer you provided.
To simplify the expression 5a − 8c + b + 3c − 9a + 6b, you need to combine like terms, which means adding or subtracting terms that have the same variables raised to the same powers.
First, let's combine terms with the variable "a":
5a - 9a = -4a
Next, let's combine terms with the variable "b":
b + 6b = 7b
Finally, let's combine terms with the variable "c":
-8c + 3c = -5c
Putting it all together, the simplified expression is:
-4a + 7b - 5c
So, your answer of -4a + 7b - 5c is correct! Good job!
