Answer:
Step-by-step explanation:
Let s represent the number of sodas sold. Then the number of hot dogs sold is (s-50) and the total is ...

2s = 268 . . . . . . . . . add 50
s = 134 . . . . . . . divide by 2
134 sodas were sold; 84 hot dogs were sold.
x = - 36
multiply both sides of the equation by - 2
x = (- 2)× 18 = - 36
