Lets try and remove the bracket by multiplying 3 with (x+4).
3(x+4)=3x+12
Now we have:
3x+12-2=2x+1
3x+10=2x+1
Lets put the variables on one side and the numbers on the other side. Every variable or number that will change signs, will have their sign changed from a + into a - and vice versa.
3x-2x=1-10
x=-9
