Hey there! I'm happy to help!
PART A
Let's look at our two equations.
y=3x-5
y=6x-8
We will solve this with substitution because we have two different values for y, so it will be be very easy to substitute.
We know that y is equal to 6x-8. This means that we can replace the y in the first equation with 6x-8 and then solve for x.
6x-8=3x-5
We add 8 to both sides.
6x=3x+3
We subtract 3x from both sides.
3x=3
We divide both sides by 3.
x=1
We can plug this x-value into either of our equations to figure out what y is.
y=6(1)-8
y=6-8
y=-2
Therefore, our solution is x=1 and y= -2.
PART B
When graphing the two equations in a systems of equation, the point where they intersect is the solution. We already have our solution, so now we will just write it as a point, which is (1,-2).
Have a wonderful day! :D
Well, if there is no restriction on how it is solved, the easiest way is to solve by guess and adjustment.
Assume everyone bought coach tickets, then
expense=15*220=3300
So there is (12930-3300)=9630 left over for them to switch to first class.
The
number employees who can switch to first class
=9630/(1290-220)
=9630/1070
=9
So there are 9 first-class tickets and (15-9)=6 coach tickets.
