What is the value of x in the equation 9 - 2x = 3?

To solve the equation ( 9 - 2x = 3 ), the goal is to isolate the variable ( x ). First, we can start by eliminating the constant on the left side. We can do this by subtracting 9 from both sides:

[ 9 - 2x - 9 = 3 - 9

] This simplifies to:

[ -2x = -6 ]

Next, to solve for ( x ), we need to divide both sides by -2:

[ x = \frac{-6}{-2} ] This simplifies to:

[ x = 3 ]

Therefore, the value of ( x ) in this equation is 3. The calculation shows that after performing the appropriate algebraic manipulations—subtracting 9 and dividing by -2—we arrive at the correct solution.
