Full solution

Q. Solve for rr.\newline3(r−7)=33(r - 7) = 3\newliner=r = _____
  1. Divide by 33: Divide both sides of the equation by 33 to isolate the term with the variable rr. Divide 3(r−7)3(r - 7) by 33 and 33 by 33. 3(r−7)3=33\frac{3(r - 7)}{3} = \frac{3}{3} r−7=1r - 7 = 1
  2. Isolate variable rr: Add 77 to both sides of the equation to solve for rr.r−7+7=1+7r - 7 + 7 = 1 + 7r=8r = 8
