Question

Simplify, if possible, by combining like terms. 23a-10a+6a

Answer 1

19a

Explanation:

"Combining like terms" just means if the variables are the same and the exponents are the same, then you add up or subtract the terms.

Like you CAN subtract
`23a-10a` because they both have the variable a and the exponent is 1 (its not written but it is just one)

You COULD NOT add (or subtract)
`5a^(2) + 11a` because they have different exponents. NOR add (or subtract)
`14x - 6a` because they have different variables.

So in your question all the terms are just a. So just subtract 23a - 10a and you get 13a.

Then add 13a + 6a to get the answer 19a
