Question

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?

Answer 1

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
 Answer:
 the player with the fewer points scores 54 points
