Question 1011687: I'm noticing a lot of the solutions are solving the wrong problems. The solution oftentimes reverses the signs of the original problem, thus demonstrating the wrong answers. For example: the problem is 6x+y=28, 3x+4y=7. However, the solution is solving for 6x-y=28, 3x-4y=7. What? There are many of these. Is anyone actually using these examples and verifying them? If so, I'm super surprised this has not been discovered and corrected. Answer by ikleyn(53938) (Show Source):
