my and Stephanie were playing a number game. Amy picked a number and told Stephanie that if she added 8 to the number and multiplied the sum by 3, it would equal 9. Which equation could Stephanie use to find the number, x?
A.
3 + (x + 8) = 9
C. 3(x+8)=9 Always make sure u do PEMDAS so since the number that Amy picked is unknown we will label it X. Next step was x added to 8 which will look like this x+8 but wants the sum multiplied by 3 so since we don't know the answer we will close it in parenthesis and multiply it by 3 which will look like 3(x+8) and lastly add the equal sign and the number 9.
