Solve for x: 2x + 5 = 3x - 4.

Explanation:
Solving a linear equation by isolating the variable is what this item tests. To find x in 2x + 5 = 3x - 4, remove the x term from one side by subtracting 2x from both sides, giving 5 = x - 4. Then get x by itself by adding 4 to both sides, which yields 9 = x. So the value of x is 9.
