Answer:
[tex]3x + 6y = 1200[/tex] is the correct linear equation.
Step-by-step explanation:
Given:
Time taken to manufacture an office chair = 3 hours
Number of office chairs produced = [tex]x[/tex]
Time taken to manufacture an office desk = 6 hours
Number of office desks produced = [tex]y[/tex]
Let us calculate, Total Time taken to manufacture [tex]x[/tex] chairs.
Suppose we manufacture 2 chairs, time taken = 3 hours + 3 hours i.e. = 6 hours
Suppose we manufacture 3 chairs, time taken = 3 hours + 3 hours + 3 hours i.e. = 9 hours
Now, we are manufacturing [tex]x[/tex] number of chairs so we have to add 3 for [tex]x[/tex] number of times:
OR
simply multiply 3 with [tex]x[/tex].
i.e. Total time taken in producing [tex]x[/tex] chairs = 3[tex]x[/tex] hours
Similarly Total time taken in producing [tex]y[/tex] desks = 6[tex]y[/tex] hours
We have a total of 1200 hours to produce this type of office chairs and desks:
So, 1200 = Total time taken in producing [tex]x[/tex] chairs + Total time taken in producing [tex]y[/tex] desks
Putting the values, we get the following:
[tex]3x+6y=1200[/tex] is the correct linear equation for the situation.
