Given : 4 balls: Football, Rugby ball, Volleyball, and Basketball.
To Find : weight of all the balls combined
Solution:
Football, Rugby ball, Volleyball, and Basketball.
Football, + Rugby ball + Volleyball, = 1310 g Eq1
Football, +Volleyball + Basketball = 1550 g Eq2
Basketball + Volleyball + Rugby ball = 1510 g Eq3
Basketball + Rugby ball + Football, = 1510 d Eq4
Equating Eq 3 & Eq4
=> Basketball + Volleyball + Rugby ball = Basketball + Rugby ball + Football,
=> Volleyball = Football = x
R = Rugby ball
B= Basketball
2x + R = 1310
2x + B = 1550
=> 4x + R + B = 2860
x + R + B = 1510
=> 3x = 1350
=> x = 450
2x + R = 1310 => R = 410
2x + B = 1550 => B = 650
Football, = 450
Rugby ball, 410
Volleyball, = 450
Basketball. 650
