6more than 5 times a number (x) is at least twenty- one

Okay, so to start you off, try to write an equation, like 5x+6=21. Then, subtract the 6 to both sides of the equal sign. This gets you 5x=15. At this point, divide the five on both sides. This will then get you x=3. I hope that that was what you were looking for. Have a great day
