To solve this equation, we need to first distribute the x on the right side of the equation:

5x - x^2 + 3 = 2x - x^2

Next, we can simplify the equation by combining like terms:

3 = 2x

Now, we can solve for x by dividing both sides of the equation by 2:

3/2 = x

Therefore, the solution to the equation is x = 3/2.
