Answer:
-4
Step-by-step explanation:
Let's put this in math notation. We can call the number x:
9x+4=8x
Subtract 8x from both sides:
x+4=0
Subtract 4 from both sides:
x=-4
Answer:
Step-by-step explanation:
For this, we will use the variable x.
9x + 4 = 8x
4 = -1x
x = -4
If they are looking for just the formula, it is 9x + 4 = 8x
If they are looking for the solved answer, it is x = -4
