We can solve this

 

5x - 4  =  3M

3x + 8  = M

 

Multiply  the second equation by 3 

 

5x  - 4  =  3M

9x + 24  = 3M

 

The right side is equal, so set the equations equal

 

5x  - 4  =  9x  + 24     add 4 to both sides, subtract 9x from both sides

 

-4x  =  28      divide both sides by -4

 

x  =  -7
