Solve for x: 2x - 3 = x + 4.

Explanation:
Solving linear equations by isolating the variable with inverse operations. To get x by itself, move terms with x to one side and constants to the other. Subtract x from both sides: 2x − x − 3 = 4, which gives x − 3 = 4. Then add 3 to both sides: x = 7. Check by plugging back: 2(7) − 3 = 14 − 3 = 11, and 7 + 4 = 11, so both sides match. Therefore, x equals 7.
