Quick Homework Help

# May I have the directions and step by step help for the simplifing, combing like terms, and solving the problem? So pretty much help for the whole problem. ⚑ Flag

Ok, so your problem is 2(m - 4) = 5m + 71. First you need to simplify.     In this case multiply 2 by (m - 4)2. you now have     2m - 8 = 5m + 73. now subtract 2m from both sides    -8 = 3m + 74. now subtract 7 from both sides    -15 = 3m5. now divide 3 by both sides6. your answer is m = -5

So basically, if you want to isolate a term on a side, you kind of do I backward pemdas, where you add or subtract the constant on the side with the variable, then multiply or divide by the coeffiecient of your x, then do the same thing within parenthases. If you have variables on both sides, all you do to get it on one side is add or subtract the variable term on either side, simplify, then solve as you would a normal equation.

Right, you want to get your two variables on one side which means they will be combined if the are the same.  Then on the other side you want your numbers.  Its pretty much similar to an equation with just one variable you just have to simplify the equation before you get to it.
