Simplify the expression \(3x - 7 + 2x + 5\)

Step 1 ：Step 1: Identify like terms. Here, \(3x\) and \(2x\) are like terms, and \(-7\) and \(5\) are like terms

Step 2 ：Step 2: Combine like terms. \(3x + 2x = 5x\) and \(-7 + 5 = -2\)

Step 3 ：Step 3: Rewrite the original expression by replacing the like terms with their sums. The simplified expression is \(5x - 2\)
