Answer:
x = 11/2
Step-by-step explanation:
Combine like terms to get -4x + 15 = -7
Subtract 15 from both sides to get -4x = -22
Divide both sides by 4 to get x = 11/2
I think it’s option 3, 1/3
Let h be hot dogs and s be sodas
h+s=221
h=s-59
s=s
s+s-59=221
2s-59=-221
2s=280
s=140
h=140-59=81
140+81=221
Answer: there were 81 hotdogs and 140 sodas sold
