Sure, here are some step-by-step solutions for a math problem: **Problem:** Solve for x: $3x+5=17$ **Solution:** Step 1: Subtract 5 from both sides of the equation to isolate the variable x. $3x+5-5=17-5$ Step 2: Simplify the left side of the equation by combining like terms. $3x=12$ Step 3: Divide both sides of the equation by 3 to solve for x. $\frac{3x}{3}=\frac{12}{3}$ Step 4: Simplify the left side of the equation by cancelling out the 3's. $x=4$ Therefore, the solution to the problem is x = 4.
