We are asked to solve the equation 4x=20.
- Remember, we need to get x all by itself.
Is x all by itself? No, there's a 4 multiplied by it.
So, we do the opposite operation.
The opposite of multiplication is..?
Division.
Thus, we divide both sides by 4.
x=5
Remember this...
Hope it helps you out! :D
