Question

 please help!!!!!

Answer 1

Let x be the number

 

Let the number be tripled:  3x

Then added to itself:  +x

the result is:  =

12 more than the number:  x + 12

 

Your equation is:

3x + x = x + 12

4x = x + 12

4x -x = 12

3x = 12

x = 4

 

Check:  3x + x = x + 12

            3(4)+4 = 4 +12

            12 + 4 = 4 + 12

            16 = 16
