When solving the equation, which is the best first step to begin to simplify the equation? = 2(x+3) = -10
O (-2)(-2)(x+3) = -10(-2)
0-3-2)(x+3) --10(-4
03(x+2) = -10
03(x+3) ---10

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
