Question

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

Answer 1

-2(x+3)=-2(x+1)-4 Start by distributing -2
-2x-6=-2x-2-4 Combine like terms
-2x-6=-2x-6 This is an obviously true statement.
if you wish, you can extend this by adding 2x and 6 to both sides getting:
0=0

Answer 2

Solution is all real numbers.
