Answer:
x = 5
Step-by-step explanation:
4x = 7 - 8x - 27
1) Combine like terms (7 and -27). So, 7 + (-27) = -20.
4x = 8x - 20
2) Subtract 8x from both sides of the equation. So, 4x - 8x = -4x.
-4x = -20
3) Divide both sides by -4. So, -20 / -4 = 5.
x = 5
You have to set up a system of equations
x+y=104
3x-y=104
Sodas = 78
Hotdogs = 26
I think it is the first one could be wrong tho
