Add 5 to both sides to get x alone and you will have your answer which is x= -3
Omitted value: The price of children ticket was omitted in the question, so i used $8 to solve. You can input the correct value and solve the same way following the steps.
Answer: 100 adult tickets must be sold.
Step-by-step explanation:
step 1
let x represent Adults
AND y represent children
Since the theater seats 250 people we have that
x+y = 250..... equation 1
Also price for Adult ticket = $11
and price children ticket =$8
With total sales at $2,300, we have that
11x + 8y= 2300----- equation 2
Step 2
Making y subject in equation 1
' x+y = 250
y= 250-x
Putting y= 250- x in equation 2
11x + 8(250-x)= 2300
11x +2000-8x= 2300
11x -8x = 2300-2000
3x= 300
x 300/3
x= 100.
To find y
x+y = 250
100+y=250
y=250-100
y=150
Therefore 100 adult tickets and 150 children tickets must be sold to get a total sales of $2,300
I believe that answer is 54
Answer:
x=2 and x=12
Step-by-step explanation:
|2x+1| = |3x-11|
2x+1 = 3x-11
2x = 3x-12
-x = -12
x = 12
2x+1 = -(3x-11)
2x+1 = -3x+11
5x+1 = 11
5x = 10
x = 2
