Answer: x=2
Step-by-step explanation:
2(5x+3)=26
Distribute the 2
10x+6=26
Subtract 6 from both sides 
10x=20
Divide both sides by 10
x=2
 
        
             
        
        
        
Answer:
(C) 220
Step-by-step explanation:
Let x represent the number of adult tickets sold and y represent the number of student tickets sold. With the information given, we can set up two equations:
 
 
 (Since for every adult ticket sold, $5 is made and for every student ticket sold, $3 is made)
 (Since for every adult ticket sold, $5 is made and for every student ticket sold, $3 is made)
In the first equation, we can represent x in terms of y:

And then, we can substitute x in the second equation for 360 - y to get:
 which simplifies to:
 which simplifies to:
 and therefore,
 and therefore,  .

<span>15 - 13(2x + 6) < 15 - 3(6x - 7)
15 - 26x - 78 < 15 - 18x + 21
-26x -63 < -18x + 36
-8x < 99
   x > -99/8
or
   x > - 12.375

To solve this, you cross multiply, then divide. In this case, we multiply 4 and 2, then divide by 3.
4 x 2 = 8
8 / 3 = 2.66
So, x is 2.66
        
             
        
        
        
Is that supposed to be x squared, or x times 2 in the beginning of the first one?
