What is the answer to 8m-5=5m+7

Expert's answer

8m-5=5m+7

Let's move all terms containing m to the left part, all the rest to the right. Keep in mind that if you move a term from one part of equation to another you should change the sign of it:

8m-5m=7+5

3m=12

Now we need to divide both parts by 3, we obtain:

m=4
