AB+BC you will get the length of AC
2x-1=7x+44 is equal to -9. The first step is to add one on both sides to get x by itself. Right now you should have 2x= 7x+45. Then you subtract 7x from both sides. You should have -5x=45. Now divided -5 on both sides. You should get the answer x=-9. By the way remember only subtract variables from other variable and regular numbers only from other regular numbers. Hope this helps, if you have any questions please comment.
