Thank for sharing!
thankss
Can someone explain it other way?
Great!
thanks!
thank you very much!
thanks, this one was pretty straightforward once you cross-multiply
yeah agreed, took me like 30 seconds
wait why is A wrong? I got y-3 over 3y somehow 😭
check your sign when you move the 3x term over, that's where it usually goes wrong
same lol, i always mess up the signs on these
Quick tip: just treat it as xy = 3(x+y) then collect the x terms on one side. The answer choices with y-3 in the denominator are a giveaway.
easy one, got it in my head. good warmup for the harder stuff later
What it tests
Your ability to manipulate linear and quadratic expressions, substitute unknowns, and solve equations under time pressure.
Common trap
Losing a sign when moving terms across the equals sign, or dividing both sides by a variable that could equal zero.
