Full solution

Q. Solve the equation.\newline1.25=0.75+r 1.25=0.75+r \newliner= r=
  1. Isolate r: 1.25=0.75+r1.25 = 0.75 + r
    Which operation should be used to isolate r?
    In 1.25=0.75+r1.25 = 0.75 + r, we should subtract 0.750.75 from both sides to isolate rr.
    Subtract 0.750.75 from both sides.
  2. Subtract 00.7575: 1.250.75=r1.25 - 0.75 = r\newline Find the value of rr.\newline 1.250.75=0.501.25 - 0.75 = 0.50\newline r=0.50r = 0.50
