Answer:
Explanation:
Let x be the number of hot dog sold
Let y be the number of soda sold
x + y = 213
And x = y - 51
Substitute x value in the first equation:
y - 51 + y = 213
2y = 264
y = 132
Find x:
x + 132 = 213
X = 213 - 132
x = 81
Therefore, the number of hotdog sold was 81
The number of soda sold was 132
