Answer: " x = 5 " .
_______________________
Solve for "x" ; Given: " -3x - 8 + 6x = 7 " ;
____________________
Combine the "like terms" on the left-hand side of the equation:

-3x + 6x = + 3x ;
__________________________
Rewrite the equation:

3x - 8 = 7 ;
________________
Add "8" to EACH SIDE of the equation:
____________________________
3x - 8 + 8 = 7 + 8 ;
____________________________
to get:

3x = 15 ;
____________________________
Divide EACH SIDE of the equation by "3" ; to isolate "x" on one side of the equation; and to solve for "x" ;
____________________________
3x / 3 = 15 / 3 ;
____________________________
x = 5 .
