Something wrong with your question!

Explanation:

Multiply the content of each bracket by the number that is outside.

#(5xx1)+(5xx4m) = (2xx3)+(2xx10m)#

#5+20m=6+20m#

Subtract #20m# from both sides giving

#5=6 color(red)(larr" THIS IS VERY WRONG")#
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#color(red)("Suppose instead that you question was meant to be:")#

#5(1-4m)=2(3+10m)#

#5-20m=6+20m#

Add #20m# to both sides

#5-20m+20m=6+20m+20m#

#5+0=6+40m#

Subtract 6 from both sides

#-1=40m#

Divide both sides by 40

#m=-1/40#
