Step-by-step explanation:
1. 21 = 6x+3
2. Subtract the 3 from one side which will cancel it out. Then go to the other side of the equation and subtract 3 from 21. The equation will now look like this - 19 = 6x
3. Now divide by 6 on one side to cancel it out. Then go to the other side and divide 19 by 6.
Answer: X = 3.16666666667
Two things to remember when doing these equations
- Think of it as trying to get x by itself
- If you add, subtract, divide, or multiply on one side of the equation always remember to do the same thing to the other side.
