Answer: " x = - 4 " .
____________
Step-by-step explanation:
____________
Method 1):
____________
Given:
" -5x − 10 = 10 " ; Solve for "x" ;
____________
Add "10" to Each Side of the equation:
____________
-5x − 10 + 10 = 10 + 10 ;
____________
to get:
____________
-5x = 20 ;
____________
Now, divide Each side of the equation by " -5 " ;
to isolate "x" on one side of the equation;
& to solve for "x" :
_____________
-5x / -5 = 20/ -5 ;
____________
to get:
" x = - 4 " .
____________
Method 2):
____________
Given:
" -5x − 10 = 10 " ; Solve for "x" ;
____________
Multiply each side of the equation by "-1" ; to get rid of the "negative value" of the "coefficient of "x" :
____________
-1 *{-5x − 10} = 10*{-1} " ;
____________
to get:
____________
[-1*-5x] − [-1*10] = -10 ;
to get:
5x − (-10) = -10 ;
to get:
5x + 10 = -10 ;
____________
Subtract "10" from Each Side of the equation:
____________
5x + 10 − 10 = -10 − 10 ;
to get:
5x = -20 ;
____________
Now, divide each side of the equation by "5" ;
to isolate "x" on one side of the equation;
and to solve for "x" ;
____________
5x / 5 = -20 / 5 ;
____________
to get:
" x = - 4 " .
___________
Method 3):
___________
Given:
" -5x − 10 = 10 " ; Solve for "x" ;
____________
Divide Each Side of the equation by: "-5" ;
____________
" " ;
____________
Simplify to:
" " ;
Simplify to:
" x − (-2) = - 2 " ;
Simplify to:
" x + 2 = - 2 " ;
____________
Now, subtract "2" from Each Side of the equation;
to isolate "x" on one side of the equation;
and to solve for "x":
____________
" x + 2 − 2 = - 2 − 2 " ;
____________
to get:
" x = - 4 " .
