What is the value for x when solving the equation −x + (−3) = x + 3 using algebra tiles?

x = -3

Step-by-step explanation:

Solving for value of x

−x + (−3) = x + 3              

-x -3 = x + 3                     [subtract x from both side]

-x -3 -x = x + 3 -x

-2x -3 = 3                       [add 3 to both side]

-2x -3 + 3 = 3 + 3

-2x = 6                          [divide both side by -2]

=

x = -3
