Please Can Anyone Solve This?? by Chrisvotel: 7:39pm On Aug 22, 2022 |
Please can anyone help me solve this math problem it's for my sister and she's submitting it tomorrow I've tried every method I know but I couldn't get the answer it's a number to words question 1) 2 is added to twice a certain number and the sum is doubled. The result is 10 less than 5 times the original number. Find the original number 2) I add 12 to a number and then double their sum. The result is one and a half times what I get when I double the original number and add 12. find the number There where 3 questions but I managed to solve one using simultaneous equations but these ones are complicated Mods please help me push this to the front page.. Thanks |

Chrisvotel: The number is x 1) 2(2 + 2X)= 5X-10 4+4X=5X-10 X= 14 show full step ooo...so she doesnt lose marks 2) (12+X) double the sum 2(12+X) 2(12+X)= (2X +12)3/2 2(24+2X)= 3 (2X +12) 48+4X=6X+36 6X-4X=48-36 X=12/2 X=6 2 Likes |
