Question

- 1/3m – 7 = 5

Answer 1

\[-\frac{ 1 }{ 3 }m - 7 = 5\]
\[\text{You want to isolate m.} ~~\text{First step is to undo the subtraction, so add 7 to both of the sides.}\]
\[-\frac{ 1 }{ 3 }m = 12\]
\[\text{Next, you want to get rid of the -1/3. }\]
\[{\text{To do so you must multiply both sides by the reciprocal of that number, which is -3.}}\]
\[m = -36\]

Answer 2

which is -3*
