I just helped you with this question! If you were confused you should have said so instead of closing the question!

OK we had 2 equations.
x+y = 56
and
y = 8 + x
do you know how to solve a system of equations?

sorta but not really

I like comparison. In both equations, solve for y=. It's already done for you in the second. Then set the two equations equal to each other, eliminating the y and solve for x.

- anonymous

so just 8 + x

- anonymous

=56

- anonymous

No because you have to solve for y in the first equation.
You get
x+y = 56
y = 56-x
and
y= 8 + x
so
8+x = 56-x
solve for x!

- anonymous

oh

- anonymous

would i first minus eight to both sides?

- anonymous

yes

- anonymous

x = 48 -x

- anonymous

now what?

- anonymous

Add x on both sides

- anonymous

ok so this gives me 48

- anonymous

alone

- anonymous

i mean 2x = 48

- anonymous

ok now divide by 2

- anonymous

24

- anonymous

can u help me with a few more

- anonymous

I'll help you with 1 more but you should be starting to be able to recognize the pattern and figure out how to solve it by yourself

ok

2.Salisbury High School decided to take their students on a field trip to a theme park. A total of 150 people went on the trip. Adults pay $45.00 for a ticket and students pay $28.50 for a ticket. How many students and how many adults went to the park if they paid a total of $4770?

- anonymous

Okay here the variables (x and y) are the number of adults and the number of students. So we can say
x = number of adults
y = number of students
These are the 2 statements:
1. A total of 150 people went on the trip
2. they paid a total of $4770
Can you turn these into equations?

- anonymous

x + y = 150
x45.00 + y28.50 = 4770

Sorry was afk for a sec. Yes that's correct. Now use substitution to solve. Solve for x or y in the first equation and plug it into the second equation

- anonymous

im not sure how to do that

- anonymous

cause first one we did comparison

- anonymous

Let's solve for y in the first equation
x+y = 150
y= 150-x
Now plug it into the second
45x + 28.5y = 4770
45x + 28.5(150-x) = 4770
now expand and solve for x

- anonymous

umm ok ive never seen that done before now though

- anonymous

OK I have to go, good luck :)

- anonymous

oh ok thanks
