How do you solve 1.2m+7.5m+2.1=631.2m+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 = 7m=63−2.11.2+7.5=60.98.7=7 Explanation: First subtract 2.12.1 from both sides of the equation to get: 1.2m+7.5m = 63-2.1 = 60.91.2m+7.5m=63−2.1=60.9 1.2m + 7.5m = (1.2+7.5)m = 8.7m1.2m+7.5m=(1.2+7.5)m=8.7m So 8.7m = 60.98.7m=60.9 Divide both sides by 8.78.7 to get: m = 60.9/8.7 = 7m=60.98.7=7 Answer link Related questions How do you solve multi step equations by combining like terms?
