Today I will explain how to solve 2x-7=15. First you need to add 7 to both sides. Add 7 with the -7 and that becomes 0. Cross that out or get rid of it because you do not need it anymore. Then add 7 to 15 and you should get 22. The equation should look like this: 2x=22. Next you will need to divide the 2 on each side as well. 2 divided by 2 is gone so get rid of it. 22 divided by 2 is 11. The equation should look like this: x=11. The answer is 11.
