Respuesta :

let's multiply both sides by the LCD of all the fractions, we only have one fraction, so the LCD will be 7 then, so let's multiply both sides by 7, to do away with the denominators.


[tex]\bf -4=\cfrac{3}{7}m-13\implies \stackrel{\textit{times 7}}{7(-4)=7\left( \cfrac{3m}{7}-13\right)}\implies -28=3m-91 \\\\\\ \stackrel{\textit{adding 91 to both sides}}{63=3m}\implies \cfrac{63}{3}=m\implies 21=m[/tex]

Solve:

-4    =    3/7m    -    13     ======>    m        =    21

Graph:   Intersection Points ====>  (21,   -4 )

Steps:

-4    =    3/7m    -    13

Switch sides:

3/7m  - 13   =   -4

Add   13 to both sides:

3/7m  - 13   +  13    =   -4   +  13

Simplify:

3/7m    =   9

Multiply Both sides  by 7:

7   *   3/7m     =    9  *   7

Simplify:

3m     =     63

Divide both sides by  3:

3m/3    =    63/3

Answer  ====>   m     =    21





Hope that helps!!!!                                : )
