set up to take X-Ci
5X = 3X +6
X = 3
3 multiplied by 5 = 15
So, took three times, the original 15
a dollar each linear equation on getting out哈哈哈哈哈

number 6 / (5-3) = 3
original badminton and table tennis, 3 * 5 = 15
set up the original badminton and table tennis X months and take over y times,
x-5y = 0
x-3y = 6
x = 15 y = 3

set quantities of t, took a total of x times
there are equations, 5x +3 x +6 = 2t
5x = 3x +6
x = 3 times, t = 15 Ge,

table tennis x
badminton y 1.x = y 2.y-3 * z = 6 3.x = 5z
the number of z
with three equations a x = 15 y = 15 z = 3
