Kevin said that if you triple his age the result will be 1 less than his mother age

which if any of these equations shows the relationship between kevin's age x and his mothers age y? choose all the correct

1.) 3x-y=1

2.) y-3x=1

3.) 3x+1=y

4.) 3x= 1-y

btw the < -- subtract

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
