Question

How do you solve `2x + 4 = 6`?

Answer 1

`x = 1`.

Explanation:

We start with:
`2x + 4 = 6`. We have to leave `x` alone. So:

1. We pass the `4` form the left, where it is adding (`+ 4`) to the right, where it will be doing the opposite, so, subtracting:
   `2x = 6 - 4`,
   `2x = 2`.
2. Now, we pass the `2` from the left, where it is multiplying (`2x` is the same as `2*x`) to the right, were it will do the opposite, dividing:
   `x = 2/2`,
   `x = 1`.

Hope it Helps! :D .
