Solve for x: 3x - 7 = 2x + 5

Explanation:
Solving a linear equation means isolating the variable so it stands alone. Start with 3x − 7 = 2x + 5. Subtract 2x from both sides to collect the x terms on one side: x − 7 = 5. Then add 7 to both sides to isolate x: x = 12. Check by substitution: 3(12) − 7 = 29 and 2(12) + 5 = 29, so both sides match. The solution is x = 12.
