OpenStudy (wolf1728):
Plugging the numbers into the formula (18 + V = 33 + 2) You can solve that now.
OpenStudy (helpplease456711):
What do I do with 18 since I can't add it with V ?
OpenStudy (wolf1728):
That is elementary algebra. Move the 18 to the right side of the equation where it becomes -18.
OpenStudy (helpplease456711):
Okay, thank you
