statement 2 gives y=2x so x+y=3x, still not a single number. but together with 1 you can solve for x. took me a sec to see it.

What this question tests

Your ability to manipulate linear and quadratic expressions, substitute unknowns, and solve equations under time pressure.

Losing a sign when moving terms across the equals sign, or dividing both sides by a variable that could equal zero.

What number is 6 more than x+yx + y x+y?(1) yyy is 333 less than xxx.(2) yyy is twice xxx.
