Q. How many solutions does this equation have?\newline−r=r+4-r = r + 4\newlineChoices:\newline(A)no solution\newline(B)one solution\newline(C)infinitely many solutions
  1. Simplify equation: Simplify the equation by moving all terms involving rr to one side.\newline−r=r+4-r = r + 4\newline−r−r=4-r - r = 4\newline−2r=4-2r = 4
  2. Solve for r: Solve for r by dividing both sides by −2-2.\newliner=4−2r = \frac{4}{-2}\newliner=−2r = -2
