Solve equation

7+3x-12x=3x+1

7+3x-12x=3x+1

We will first make all the numbers which have x in go to the left.

So 7+3x-12x-3x, we make the 3x negative since to make it move it needs to change.

Then we will make all the sevens go to the right, so 3x-12x-3x=1-7.

So now it is much easier to figure out.

-12x=-6
