I don't know how to do combing like terms someone help me!!!!

1 answer:

Just add them together. For example if you have 4x and 7x you would just do 4x+7x and get 11x. You can only add them because they are like terms, meaning that they share a variable.

Q(a+y)=67y+93 solve for y

sasho [114]

$Q(a+y)=67y+93\\
aQ+Qy=67y+93\\
Qy-67y=-aQ+93\\
y(Q-67)=-aQ+93\\
y=\dfrac{-aQ+93}{Q-67}\\
\boxed{y=-\dfrac{aQ-93}{Q-67}}$
