thanks, helpful!
wait why is it E and not D? i keep messing up the sign flip when i rearrange
if you add x to both sides you get y < -x, which is the same as -x > y. the inequality direction doesn't change since you're adding, not multiplying by a negative
easy one but the trap answer choice got me for a sec lol. gotta remember they can ask 'must be true' and just rearranging is the whole game
is this really sub-505? feels like the kind of thing i'd overthink on test day. any tips for not second-guessing these?
just trust the algebra, add x to both sides and you're done. don't test numbers unless you're stuck
What it tests
Your ability to solve and combine linear inequalities and reason about ranges of values.
Common trap
Failing to flip the inequality sign when multiplying or dividing by a negative, or missing an inclusive/exclusive endpoint.
