In a game, the two players scored a total of 121 points. one player had 13 more points than the other player.  how many points did the player with the fewer points score?

We are going to write the following variables:
 x: points for player 1
 y: points for player 2
 We write the following system of equations:
 x + y = 121
 y = 13 + x
 Solving the system we have:
 Step 1:
 x + (13 + x) = 121
 2x + 13 = 121
 x = (121-13) / (2)
 x = 54
 Step 2:
 y = 13 + 54
 y = 67
 
 the player with the fewer points scores 54 points
