solve this equation. Tell whether the answer turns out to be a false equation or identity.

3+x=-x-8

1 answer

To solve the equation 3 + x = -x - 8, we can start by isolating x on one side of the equation.

First, add x to both sides of the equation to get rid of the "-x" term on the right side:

3 + x + x = -x - 8 + x

This simplifies to:

3 + 2x = -8

Next, subtract 3 from both sides of the equation to isolate the x term:

3 + 2x - 3 = -8 - 3

This simplifies to:

2x = -11

Dividing both sides of the equation by 2 gives us the solution for x:

x = -11 / 2
x = -5.5

Therefore, the solution to the equation 3 + x = -x - 8 is x = -5.5.

This is not a false equation or identity, as the solution is a specific value for x that satisfies the original equation.
