Question

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

Answer 1

-3.

Hope this helped.

Answer 2

x = -3

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]

`(-2x)/(-2)` =
`(6)/(-2)`

x = -3
