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 " .

The top row of matrix A (1, 2, 1) is multiplied with the first column of matrix B (1,0,-1) and the result is 1x1 + 2x0 + 1x -1 = 0 this is row 1 column 1 of the resultant matrix
The top row of matrix A (1,2,1) is multiplied with the second column of matrix B (-1, -1, 1) and the result is 1 x-1 + 2 x -1 + 1 x 1 = -2 , this is row 1 column 2 of the resultant matrix
Repeat with the second row of matrix A (-1,-1.-2) x (1,0,-1) = 1 this is row 2 column 1 of the resultant matrix, multiply the second row of A (-1,-1,-2) x (-1,-1,1) = 0, this is row 2 column 2 of the resultant
Repeat with the third row of matrix A( -1,1,-2) x (1,0, -1) = 1, this is row 3 column 1 of the resultant
the third row of A (-1,1,-2) x( -1,-1,1) = -2, this is row 3 column 2 of the resultant matrix
Matrix AB ( 0,-2/1,0/1,-2)
Answer:
1,3,9
Gcf: 9
Step-by-step explanation:
Answer: The distance between the two numbers is 14 because to get to zero from -6 you will add 6 to get zero then you will add eight to get 14.
