Question 1018917: 4(2n+4=6(8n+1)+9
8n+16=6(8n+1)+9
8n+16=48n+6+9
8n+16=48n+15
8n16-48n=48n+15+48
8n+16=15
8n+16-16=15-8
8n=7 or 7/8

4%282n%2B4%29=6%288n%2B1%29%2B9----------included missing parenthes
8n%2B16=6%288n%2B1%29%2B9
8n%2B16=48n%2B6%2B9
8n%2B16=48n%2B15----the last correct step
-
...and then you went wrong. These steps are all wrong below. Start from the last step above, and continue from there and you should be able to do the correct steps.
(these here are the wrong ones)
8n16-48n=48n+15+48
8n+16=15
8n+16-16=15-8
8n=7 or 7/8
