Step-by-step explanation:
well, it is supposed to be -3.
but you are right. something is wrong or missing here.
5x + 3 = 4x
x + 3 = 0
x = -3
maybe a "+ 1" is missing on the right side ?
5x + 3 = 4x + 1
gives us
x = -2
[Add] 1.
-9h = 30 + 15
[Simplify] 2.
-9h = 45
[Divide] 3.
h = - 45/9 ( A negative Divide)
[Answer] 4.
h = -5

Answer:
see the explanation
The number of hot dogs that were sold is 15 and the the number of sodas that were sold is 75
Step-by-step explanation:
Let
x ---> the number of hot dogs that were sold
y ---> is the number of sodas that were sold
we know that
You sold a total of 90 hot dogs and sodas combined
so
----> equation A
You made a total of $105
so

isolate the variable y
----> equation B
substitute equation B in equation A

solve for x

Find the value of y (equation B)

therefore
The number of hot dogs that were sold is 15 and the the number of sodas that were sold is 75
