Answer:
V = -9
Step-by-step explanation:
-15V - 40 = 23 - 8V
The objective is to get V alone. To do this, first subtract -15V from both sides. Since -15V is a negative, subtracting it will be adding a positive.
-40 = 23 + 7V
Now that there is only one term with the variable V, subtract 23 from both sides.
-63 = 7V
Finally, divide both sides by 7 to get V completely isolated.
-9 = V.
The final answer is V = -9.
