Answer:
6 grapples
Step-by-step explanation:
x = number of wins
y = number of ties
y = 15 - x
48 = 5x + 2y
48 = 5x + 2(15 - x)
48 = 5x + 30 - 2x
48 = 3x + 30
18 = 3x
x = 6

Given:

To remove decimal, divide first equation by 10 and second equation by 100

Now opening the root,





Hence, the answer is 
Remember
|x| makes x posotive
5|2x-2|+8=18
minus 8 both sides
5|2x-2|=10
divide both sides by 5
|2x-2|=2
assume
2x-2=2 and 2x-2=-2
2x-2=2
add 2
2x=4
divide 2
x=2
2x-2=-2
add 2
2x=0
x=0
x=0 or x=2
