Answer:y=24 and x=10
Step-by-step explanation:
To find the value of x and y in x=3x-20 and y=-6+30
We gets
y=24
To get x
x=3x-20
Collect like terms
x-3x=-20
Divide through by -2
-2x=-20
x=10
Let x be the number of child tickets he bought
Let y be the number of adult tickers he bought
① x+y=7 (child tickets+adult ticket=7 tickets in total)
② 2x+4y=24 (price of child tickets+price of adult tickets=$24 in total)
We may simply the second equation since all of the coefficients are divisible by 2.
① x+y=7
② x+2y=12
We can now use elimination by multiplying the second equation by -1.
② -(x+2y=12)
② -x-2y=-12
① x+y=7
② -x-2y=-12
Now putting the equations together,
-y=-5
y=5
x=2
Therefore he bought 2 child tickets and 5 adult tickets

When they say quotient, they want a fraction, so the answer for that would be

and the decimal form of that would be 0.6. You can get that from dividing 6 by 10 and solving with long division.
