Answer:
Hi there!
The answer to this question is 3
Step-by-step explanation:
You first distribute the four into the parenthesis to get: 12x-24+15+ 27
Next you add -24 to 15 to get: -9 your equation should now look like 12x-9=27
Then you add 9 on both side to get 12x=36
Last you divide twelve on both sides to x=3
