Question

Solve for x.
2x - 9 = 6 + 3x
x = [?]

Answer 1

3x - 2x = -9 -6
x = -15

so x equals -15

Answer 2

Hello !

Answer:

`\boxed{\sf x=-15}`

Explanation:

We are looking for the value of x that verifies the following equation :

`\sf 2x-9=6+3x`

To do this, we will have to isolate x.

Let's start by substracting 3x from both sides of the equality.

`\sf 2x-9-3x=6+3x-3x`

Then combine like terms :

`\sf -x-9=6`

Now let's add 9 to both sides :

`\sf -x-9+9=6+9\\-x=15`

Finally, let's multiply both sides by -1 :

`\sf-1*(-x)=-1* 15\\\boxed{\sf x=-15}`

Have a nice day ;)
