Question

Simplify the following expression :
8x-10y+5z-5x-16+6y

a) 3x-6y+11z
b) 13x-6y+11z
c) 13x-26y+11z
D)3x-26y+11z

Answer 1

add like terms to each others

Answer 2

how though ?

Answer 3

8x-5x=?

Answer 4

Like terms are terms that have the same variables.
For example, in 5x + 2y + 6x - 7y, there are two sets of like terms.
The terms 5x and 6x are like terms. The terms 2y and -7y are also like terms.
You can move the like terms together, then you combine them.

\(5x + 2y + 6x - 7y\)

\(= 5x + 6x + 2y - 7y\)

\(= 11x - 5y\)

That is the final answer. Since 11x and -5y are not like terms, they can't be combined.

Answer 5

Examples: 8x and 5x are "like terms" and can be combined. 8x-5x=3x.
8x and 5y are not like terms and must be left as they are.
