Question

At a basketball game, a vendor sold a combined total of 142 sodas and hot dogs. The number of sodas sold was 38 more than the number of hot dogs sold. Find the number of sodas sold and the number of hot dogs sold

Answer 1

x represents the number of sodas
y represents the number of hot dogs

142 = x + y
x = 38 + y

Substitute x in the first equation

142 = 38 + y +y
142 - 38 = 2y
104/2 = 2y/2
y =52

x = 38 + 52
x = 90
