How do you find the value of x?

Answer 1

If you have x in an expression, then you can't solve for x.

It depends on the equation you have when solving for x. Whatever equation you have, you'd usually isolate x to one side of the equation with all other terms on the other side.

For example,

3x + 6 = 12.

To solve for x, you'd subtract 6 then divide 3 from both sides:

3x + 6 - 6 = 12 - 6

3x = 6

3x/3 = 6/3

After simplifying, your final answer would be x = 2 for this sample equation.
