3x + 6y = 18 -6y
3x = 18 - 6y Divide by 3
3x/3=18/3-6y/3 Simplify
x=6-2y
Now we check by plugging in the value of x.
3(6-2y)+6y=18 simplify
18-6y+6y=18 simplify more
18=18.
NOW we know for sure that this is correct
x=6-2y
Okay so let’s start by figuring what the total number of people is. To get that we add 24 and 30.
24+30= 54
So we have a total of 54 people.
Now, how many children are there?
30 children... which means the ratio is 30:54
Thirty children to fifty four people total at the museum.
Hope this helps!

8 - 4(x - y) = 2x + 6
8 - 4x + 4y = 2x + 6
-4x - 2x + 4y = 6 - 8
-6x + 4y = -2
6x - 4y = 2 <====
<span>Solution above is incorrect, simplify as follows:
-(7c-18)-2c > 0
-7c+18-2c > 0
-9c > -18
c < 2</span>
