Answer:
2x + 20
Step-by-step explanation:
To simplify, combine like terms. All that means is combine the things with the xs and combine the ones that are just numbers. So 4x - 2x is 2x and 12 + 8 is 20. You always write the terms with the x first, so you wouldn't write 20 + 2x. Although that is correct, you always write the term with the x first. So, 2x + 20
Answer:
2x + 20
Step-by-step explanation:
[tex]12 + 4x -2x + 8\\\rule{150}{0.5}\\4x - 2x + 12 + 8\\\\\\\rightarrow\text{4x and -2x are like terms. 12 and 8 are also like terms.}\\\\\\\boxed{2x + 20}[/tex]
Hope this helps.
