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
