Question:

Solve for X: X+X+4 = 10

Colin B.

Solution: X = 3 Explanation: Start off by combining the X's on the left side of the equation. This results in 2X+4 = 10. Then subtract 4 from both sides to get X by itself. This leaves you with 2X = 6. Then divide both sides by 2 which gives you the answer of X = 3

Question:

Solve for X: X+9 = 18-2X

Colin B.

The Solution to this equation is X=3 Explanation: To solve this equation you must start by getting all of the X's on the same side of the equation. This is done by adding 2X to both sides. After that is done you are left with 3X+9 = 18. Then you want to get the X's to be all by themselves on one side of the equation so you subtract 9 from both sides making the equation 3X = 9. Finally, you divide both sides by 3 to solve for X. You are left with the answer of X=3.
