Answer 3

To solve the equation 2x - 9 = 3, we need to isolate the variable x. Here's how we can do it step by step:

Step 1: Add 9 to both sides of the equation to get rid of the -9 on the left side: 2x - 9 + 9 = 3 + 9 This simplifies to: 2x = 12

Step 2: Divide both sides of the equation by 2 to solve for x: (2x)/2 = 12/2 This simplifies to: x = 6

Therefore, the solution to the equation 2x - 9 = 3 is x = 6.

I hope this helps! Let me know if you have any further questions.
