4y - x = 5 + 2y ..... (1)
3x + 7y = 24 ..... (2)
by grouping like terms in (1)
4y - x = 5 + 2y
4y - 2y - x = 5
<span>-x + 2y = 5 </span> ..... (1a)
by multiplying (1a) through by -3
(-3)(-x) + 2(-3)y = 5(-3)
3x - 6y = -15 ..... (1b)
by subtracting 1a from 2
3x -3x + 7y - (-6y) = 24 - (-15)
13y = 39
⇒ y = 3
by substituting y=3 into (2)
3x + 7(3) = 24
3x = 24 - 21
3x = 3
⇒ x = 1
∴ solution to the system is x=1 when y = 3
Conner played a total of 6 +3 + 6 = 15 games. He won or tied 6+ 3 = 9 games.
His percentage is 9/15 = 0.6 x 100 = 60%
April played 5+7+4 = 16 games and won or tied 5 +7 = 12 games.
Her percentage is: 12/16 = 0.75 x 100 = 75%
Tony played 20 games and won or tied 14.
His percentage is: 14/20 = 0.7 x 100 = 70%
