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
