Q. What value of rr is a solution to this equation?\newliner−3=3r - 3 = 3\newlineChoices:\newline(A)r=6r = 6\newline(B)r=7r = 7
  1. Addition to cancel −3-3: Given the equation r−3=3r - 3 = 3, we want to isolate rr to find its value.\newlineTo do this, we add 33 to both sides of the equation to cancel out the −3-3 on the left side.\newlineCalculation: r−3+3=3+3r - 3 + 3 = 3 + 3
  2. Solve for rr: After adding 33 to both sides, we get r=6r = 6.\newlineThis is because −3+3-3 + 3 cancels out to 00 on the left side, and 3+33 + 3 equals 66 on the right side.\newlineCalculation: r=6r = 6
