Answer:
2 game, $12
Step-by-step explanation:
Given data
Showplace Lanes charges
$4.50 per game as well as
$3 for shoe rental
Let the number of games be x
let the total charge for x games be y
y= 4.5x+3-----------1
Westgate Bowling charges
$4 per game and $4 for
shoe rental
Let the number of games be x
let the total charge for x games be y
y= 4x+4-----------2
Equate 1 and 2
4.5x+3= 4x+4
collect like terms
4.5x-4x= 4-3
0.5x= 1
divide both sides by 0.5
x= 1/0.5
x= 2 games
put x= 2 in equation 1 or 2
y= 4x+4-----------2
y= 4*2+4
y= 8+4
y= $12
-2x+2y=6
7x-8y=-27
5x-6y=-21
-x+y=3
6x-7y=-24
6x-7y=-4(-2x+2y)
6x-7y=8x-8y
-6x from both sides:
-7y=2x-8y
add 8y to both sides:
y=2x
-2x+2y=6
2y-6=2x
2y-6=-12
-6-6=-12
y=-3
x=-6
