Q. Combine the like terms to create an equivalent expression:\newliner+(−5r)=0r+(-5r)=\boxed{\phantom{0}}
  1. Combine like terms: Combine the like terms by adding the coefficients of rr.r+(−5r)=1r+(−5r)=(1−5)r=−4rr + (-5r) = 1r + (-5r) = (1 - 5)r = -4r
  2. Check for errors: Check for any mathematical errors in the previous step.\newline1−5=−41 - 5 = -4, so the calculation is correct.
