4x + 5 = 3x

x = -5           

1. Subtract 4x from both sides     4x + 5 = 3x  

2. Problem reads now.......................... 5 = -1x  or -x

3. Divide -1 from both sides

4. Problem reads now........................-5 = x  

You can check your problem to see if your're correct by putting  (-5 )  in place of  (x )  in the problem. 4(-5) + 5 = 3(-5)

                    -20 + 5  = -15

                         -15    = -15                                                                                                                                                                   

 4x + 5 = 3x

i.e. 4x - 3x = -5

So, x = -5

Hope this helped you to some extent.

good job. Now try quantum physics. If i can pass it , you can.
