Nina [5.8K]

Let x be the number of hours ling work on monday.

We know that she worked three more hours on tuesday that in monday, this can be express as :

 x+3

We also know that in wednesday she worked on more hour than twice the number on mondays, this can be expressed as:

2x+1

The total number of hours she worked this three days in two more than five the number of hours she worked on monday, this can be express as :

5x+2\\

Now , once we have all the expressions we add the expressions of the days and equate them to the total

x+(x+3)+(2x+1)=5x+2

Now we solve the equation

x+(x+3)+(2x+1)=5x+2\\x+x+3+2x+1=5x+2\\4x+4=5x+2\\5x-4x=4-2\\x=2

Therefore , she worked 2 hours on monday.
