Question 13-18 & 22-27 will all be answered the same way, so i will walk you through question 13: (6,4) y=3x-2

(x,y)=(6,4)

now that we know the first number in the parenthesis is the x value and the second number in the parenthesis is the y value we can plug it into the equation. (x=6,y=4)

4=3x-2 (add two to each side)

4+2=3x

6=3x (divide 3 from each side)

x=2

---------------

y=3(6)-2

y=18-2

y=16

-------------------
answer: (2,16)

now apply the same principles to the other problems!!! hope this helped!!!

Mr. frankel bought 7 tickets to a puppet show and spent $24. he bought a combination of child tickets for $2 each and adult tick

nydimaria [60]

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
