Greta and Xavier, the boy she was babysitting, were playing basketball together. Her score was 32 points, and his score was 19 p

oints. Greta wanted to make the game more fair, so she called a time-out and modified the rules a bit. Greta explained that, for the rest of the game, she would get 3 points per basket, and Xavier would get 4 points per basket. Then they played a bit longer. After the time-out, they both made the same number of baskets and ended up with a tied score. How many baskets did each person make after the time out? How many points did each person have at the end?

Let the number of baskets be x
Let the number of points be y

32 +3x = y
19 + 4x = y

Rearrange both equations then solve them as simultaneous equations
32 = y - 3x
19 = y - 4x

y - 3x = 32
- y - 4x = 19

x = 13

Substitute x into one of the equations
y - 3x = 32
y - (3 x 13) = 32
y - 39 = 32
y = 32 + 39
y = 71

Number of baskets (x) = 13
Number of points (y) = 71
