I realized, sometimes when I post a question, a Guest comes and answers it, but puts no explanation, and they are always wrong.
2, 4, 2 is incorrect
1, -7 is incorrect
I already said thank you, and I gave Geno a point.
Thank you for leading me to the right solution.
What do you mean by 3 points?
I never tried to be rude to Geno. I never said that I would take all the credit. You could have said that I forgot to thank Geno.
I accidentally posted the same question twice because my internet was acting slow.
Therefore the equation should be (x+7)(y-1)=-10.
I see what you did wrong when you expanded y(x + 7) = x - 3 and got xy - 7y = x - 3, the -7 should have been a +7.
I tried the answer -7, -1, 4. But it was incorrect.
I'm sorry, but your answer is incorrect.
