Factor out X from the expression
Using 
, factor the expression
Write all numerators above the Least Common Denominators x ( x - 3 ) ( x + 3 )
Multiply the parentheses
When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression
Distribute -x through the parentheses
Using 
, simplify the product
Collect like terms
Subtract the numbers
Distribute x through the parentheses
Write 7x as a sum
Factor out X from the expression
Factor out 2 from the expression
Factor out x + 5 from the expression
Hope this helps...

Answer:
The operations you see with you eyes are multiplication and addition.
4 times X plus 2 = 10
The operations you don't see are Subtraction and Division.
4x+2=10
Subtract 2 from both sides.
4x+2−2=10−2
4x=8
Divide both sides by 4.
4x/4 = 8/4
x=2
You will divide the 12 by 28: 12/28 and that equals 3/7
Correct answer is C.
Line
intersects y-axis at -2 and passes through the point (3,-1).
Line must be dashed, because the inequality sign is ">".
Point (0,0) must lie in the solution set because it satisfies inequality

Answer:
adult tickets = 17, children tickets = 9
Step-by-step explanation:
Let x be the number of children and y the number of adults
Then given that 26 tickets are sold, we can write
x + y = 26 → (1)
Given that ticket cost was $194 we can write
5.5x + 8.5y = 194 → (2)
Rearrange (1) expressing y in terms of x by subtracting x from both sides
y = 26 - x → (3)
Substitute y = 26 - x into (2)
5.5x + 8.5(26 - x) = 194 ← distribute and simplify left side
5.5x + 221 - 8.5x = 194
- 3x + 221 = 194 ( subtract 221 from both sides )
- 3x = - 27 ( divide both sides by - 3 )
x = 9
Substitute x = 9 into (3) for corresponding value of y
y = 26 - 9 = 17
Hence number of adult tickets sold = 17
number of children tickets sold = 9
