How to get x alone

subtract any constants then divide

Step-by-step explanation:

if ur equation is y=3x+9

subtract nine from both sides to get - 9=3x

then divide an you will end up with x=-3

To get x alone, you need to move the rest of the numbers to the other side.

Step-by-step explanation:

So, if a number is being added, like 3 = x + 5, you need to subtract that number from both sides. If its being multiplied you need to divide, and so on.
