Question

3 + m/9 =10

Answer 1

First, you must isolate the variable you are solving for. This can be done by subtracting 3 from both sides of the equation:
\[m/9 = 7\]

Answer 2

Because m is divided by 9, you must multiply both sides by 9 (remember that multiplication undoes division), in this case \[m= 7*9\]

Answer 3

Also think about it this way, m is multiplied by (1/9) technically, so in order to get m by itself, you multiply (1/9) by 9, which equals (9/9) = 1
