Answer:
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
<u>Two things to remember when doing these equations</u>
- 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.
-degree polynomial in the denominator, its numerator must have at most a polynomial of degree
