Answer:
x=1/14 and y=1/12
Step-by-step explanation:
7x+5y+12+7x+7y=14
⇒14x+12y=2
and set x and y in 0
then you will have 14*(1/7)=2 and 12*(1*6)=2
and you want somthing that makes x + y =2
so you sett 14*x=1 and 12*y=1
that is if i did noy misunderstanding the question

Answer:
363-138=-5x
Step-by-step explanation:
Let c = cost
We know that the total cost is $363:
363-??????
We also know that he spent $138 on parts:
363-138?????
And we are solving for the cost of labor per hour:
363-138=5x
We can use this equation to find the total cost of labor per hour.
Hence, your equation will be 363-138=5x
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 :

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

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 :

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

Now we solve the equation

Therefore , she worked 2 hours on monday.
