How do you solve #1.2m+7.5m+2.1=63#? Algebra Linear Equations Multi-Step Equations with Like Terms 1 Answer George C. Jun 18, 2015 #m=(63-2.1)/(1.2+7.5)=60.9/8.7 = 7# Explanation: First subtract #2.1# from both sides of the equation to get: #1.2m+7.5m = 63-2.1 = 60.9# #1.2m + 7.5m = (1.2+7.5)m = 8.7m# So #8.7m = 60.9# Divide both sides by #8.7# to get: #m = 60.9/8.7 = 7# Answer link Related questions How do you solve multi step equations by combining like terms?
