Question

How do you solve `2x + 9+ 3x + x = 5x + 6`?

Answer 1

`x=-3`

Explanation:

Combine like terms,

`2x+9+3x+x=5x+6`

`6x+9=5x+6`

Remove `x` from one side,

`x+9=6`

`x=-3`

Answer 2

`x = -3`

Explanation:

`2x + 9 + 3x + x = 5x + 6`

First, we need to combine "like-terms," or we need to combine all the `x` values and all the numbers.

We know that `2x`, `3x`, and `x`, are all like terms on the left side of the equation, so let's add them all together:

`6x + 9 = 5x + 6`

Now, we find `x` by putting all the `x`-values to the left side of the equation and the numbers on the right.

So we subtract `5x` on both sides of the equation and get `x`.
We subtract `9` on both sides of the equation and we get `-3`.

Therefore...
`x = -3`

Hope this helps!
