Can you assist me in working out the equation 9+x=-2x-9?

Question

Can you assist me in working out the equation?

Answer 1

9+x = - 2x-9

add 2x both sides

9+3x = -9

subtract 9 from both sides

3x = -18

divide 3 both sides

x = -6

Answer 2

9+x=-2x-9

=2x+x=-9-9

=3x=-18

=x=-6

Answer 3

9 + x = -2x - 9

Move the 9 on the left to the other side by subtracting both sides by 9:

x = -2x - 18

Move the -2x to the other side by adding both sides by 2x:

3x = -18

Divide by sides by 3 to get x by itself:

x = -6

Answer 4

well add the -9 to both side so its 18+x=-2x then combine the x or isolate it by subtracting x from both sides and you get -3x=18 or 3x=-18 then devide by 3 and your answer is x=-6
