How do you write twice the sum of a number x and 8?

𝘛𝘸𝘪𝘤𝘦 means to multiply by 2. 𝘚𝘶𝘮 means to add together. So 𝘵𝘸𝘪𝘤𝘦 𝘵𝘩𝘦 𝘴𝘶𝘮 means to take whatever you're adding together and then multiply this result by 2. So your sum would be X+8. Multiplying this by 2 would give you 2X+16. Another way to write your answer would be to put parentheses around the X+8. That's because you need to do this part first. So another way to write your answer would be 2( X+8 ).
