Katy tried to solve an equation step by step. r−3=14.3 r−3+3=14.3−3 Step 1 r=11.3 Step 2 Find Katy's mistake? Choose 1 answer: (A) Step 1 (B) Step 2 (C) Katy did not make a mistake

Step 1: Add 3 to both sides: Katy starts with the equation r−3=14.3 and wants to isolate r. To do this, she adds 3 to both sides of the equation in Step 1. Calculation: r−3+3=14.3+3 Math error check: Step 2: Simplify and Add: In Step 2, Katy simplifies the left side by combining like terms (r−3+3) which results in r, and on the right side, she adds 14.3 and 3. Calculation: 14.3 + 3 = 17.3 Math error check:
