how do you figure out the problem 5x-1=x+15

Question

anonymous · Answer

first subtract x from the right side and subtract it from the right. So it's 4x-1=15. Then add one to both sides so its 4x=16. Divide both sides by 4. x=4

sorry *subtract x from left and right

so I subtract x from left to right 
so it is like this 5x-1=x+15-x

Am I right or wrong

Well usually you just right it underneath. So like 5x-1=x+15
                                                                        -x     -x
                                                                   -------------
                                                                      4x-1=-15
                                                                          +1   +1
                                                                          4x=16
