Let
chees club=x
computer club=3x+50
computer club sells 134 pins
=>3x+50=134
=>3x=134-50
=>3x=84
=>x=84/3
=>x=28
Therefore, the chess club sells 28 pins

let x be the number of pins sold by the chess club. since computer clubs sells 134 pins and the number of pins sold by the computer club is 50 more than 3 times the number of the chess club, then you will get the equation:
134=50+3x, to get the equation, transpose the constant in the other side:
134-50=3x, then divide both sides by 3:
x=(134-50)/3
The chess club sold 28 pins

let the number of pins sold by chess club = x
the number of pins sold by computer club = 3x+50
so 3x + 50 = 134
3x = 134-50
3x = 84
x = 84/3 = 28

= (134 - 50) / 3
= 84 / 3
= 28
