You can put this solution on YOUR website!
you start from the number -12 on the number line and then you go 7 units to the right of that and you land on -5

this is the same as saying that -12 + 7 = -5

here's your number line: 

numbers
    -12 -11 -10 -9  -8  -7  -6  -5  -4  -3  -2  -1   0   1   2   3   4   5
------------------------------------------------------------------------------
     '   '   '   '   '   '   '   '   '   '   '   '   '   '   '   '   '   '

     a (you start here)

         1   2   3   4   5   6   7   (you move 7 units to the right)

                                 b   (you end up here)


you started at a which was the number -12.
you move 7 units to the right and you ended up on b which is the number -5
