Question 971187: 2x-13=27
Answer by josh_jordan(263)   (Show Source):
You can put this solution on YOUR website! To solve for x, we need to get x on one side of the equal sign and everything else on the other side of the equal sign. So, the first thing we need to do is ADD 13 to both sides of the equal sign:
2x - 13 + 13 = 27 + 13 -----> 2x = 40
Finally, divide both sides by 2:
2x/2 = 40/2 -----> x = 20
Answer: x = 20
