Find the value of x if 81=3x

here ,

81=3x

or , 81/3=x

or,27=x

hence ,the value of x=27

×=27

Step-by-step explanation:

81/3=3×

27=×

hence

×=27

In order to find the breakeven number of game rentals, we need to find the point at which the costs are equal. To do this, we set two expressions as a function of the number of games, equate them, and solve.
   For Fun Guys, cost C = 20 + 6.5g, where g is the number of games
 For Game Bank, C = 50 + 3.5g
Equating -> 20 + 6.5g = 50 + 3.5g -> 3g = 30 -> g = 10
   At 10 games, the cost will be the same for both stores, and that cost is 50 + 3.5* 10 = 20 + 6.5*10 = $85.
