Solve 28m+21=413 thanks!

14

Step-by-step explanation:

28m + 21 = 413

28m = 413 - 21

        = 392

m = 392/28

   = 14

Therefore m is 14 :)

Yes, when distributing a variable to another variable in an algebraic equation, you multiply the exponents or add an exponent to the number. For example, when you multiply x and x^2, the product would be x^3. When you multiply 2z and 3z, the product would be 6^2. (When you multiply two variables with no exponents, you are essentially squaring the number.)
