Question

Solve for x: -2(x+3) = -2(x+1) -4

Answer 1

The given expression is

$-2(x+3)=-2(x+1)-4$

First, we use the distributive property to get rid of the parenthesis.

$-2x-6=-2x-2-4$

Now, we sum 2x on each side

$\begin{gathered} -2x-6+2x=-2x-6+2x \\ -6=-6 \end{gathered}$

As you can observe, the variables were eliminated and the resulting equation is true. This means the equation has infinite solutions.
