63 :(5X - 3X - 1)=21:3​
Crazy boy [7]

Answer:

x = 5

Step-by-step explanation:

Given that,

63:(5x-3x-1)=21:3\\\\or\\\\\dfrac{63}{(5x-3x-1)}=\dfrac{21}{3}\\\\\dfrac{63}{(2x-1)}=7

Cross multiplying both sides,

63=7(2x-1)\\\\9=2x-1

Taking like terms together,

10=2x\\\\x=5

So, the value of x is equal to 5.

Could I get some help?
balandron [24]

Answer:

#adult tickets sold = 346

#student tickets sold = 812

Step-by-step explanation:

let 'x' = # adult tickets sold

let 'y' = # students tickets sold

System of Equations:

x + y = 1158

5x + y = 2542

I used the elimination method and multiplied the first equation by -1

  -x - y = -1158

+<u> 5x + y = 2542</u>

  4x  =  1384

   x = 346

346 + y = 1158

y = 812
