x = 5

Work Step by Step

1. To solve this equation, we have to bring the X terms and Constant Terms to separate sides. 2. I took the X terms to the left and Constants to the right. 3. Doing what I said above, you should get -4x + 7x = 9 + 6. 4. Simplifying this is 3x = 15. 5. Solving for X equals X = $\frac{15}{3}$ which equals 5.
