Answer: x = 3
Step-by-step explanation: To solve for x in the equation you see here, our goal is to get x by itself.
Our first step will be to isolate the term containing x which in this case is 2x. To isolate 2x, we have to get rid of this +3 by subtracting from both sides of the equation.
On the left, +3 -3 cancels and we're left with 2x. On the right, 9 - 3 simplifies to 6.
So now we have the equation 2x = 6.
To get x by itself since it's being multiplied by 2, we just to divide by 2 on both sides of the equation. On the left, the 2's cancel and we're left with x. On the right, [tex]\frac{6}{2}[/tex] simplifies to 3 so our answer is x = 3.
