Sagot :

add 4x to both sides and get
13 = 1 + 3x
12 = 3x   [from subtracted 1 from both sides]
x = 4      [from dividing 3 from both sides]

therefore your answer would be  x = 4
13-4x=1-x
First,I would move my x's to the right and my numbers to the left so...

13-4x=1-x
   +4x   +4x
-------------------
13=1+3x
-1   -1
----------------
12=3x 

Now, you would divide 3 from both sides.

12=3x
---- ----
3     3
Solution: 4=x

To check the solution, plug in 4 for x.
13-4(4)=1-4
13-16=-3
-3=-3

The  solution works, therefore
x=4
