How do you solve #12r+34=-6r-(-9)#? Algebra Linear Equations Equations with Variables on Both Sides 1 Answer salamat Jun 16, 2017 #r = - 25/ 18# Explanation: #12r + 34 = - 6r - (- 9)# add #6r# to both sides #12r + 34 + 6r = - 6r + 9+ 6r# #18r + 34 = 9# minus #34# to both sides #18r + 34 - 34 = 9 - 34# #18r = - 25# divide by #18# to both sides #(18r)/18 = - 25/ 18# #r = - 25/ 18# Answer link Related questions How do you check solutions to equations with variables on both sides?
