Answer:
x = - 6/7
Step-by-step explanation:
To start, 1x is just 1 times x, which you can just write as x.
x+3 = 8x+9
Then, you can bring x over to the other side of the equation, meaning it becomes -x. You can also think about subtracting x from both sides so it cancels out on the left.
3 = 8x+9-x
Next, do the same for the 9, so your equation looks like this:
3-9 = 8x-x
Just simplify it:
-6 = 7x
Finally, divide -6 by 7 to find x.
So, x = -6/7
