-5x + y = -12- 3x + 6y = -12Since both of expressions have a value of -12, their sum is - 24. This is true only whenx = 20/9 and y = -8/9.-5x + y = -12y = 5x - 12- 3x + 6y = -12-3x + 6(5x - 12) = -12-3x + 30x - 72 = -1227x = 60x = 60/27x = 20/9y = 5x - 12y = 5(20/9) - 12y = 100/9 - 12y = (100 - 108)/9y = -8/9

Oh, dude, it's like you just gotta pull out the common factor, which in this case is 4. So, you're left with 4(x + 3y). And that's it, like, you're done. Easy peasy lemon squeezy.
y^2 - 12y + 36 = 9 subtract 9 from each side y^2 - 12y + 27 = 0 easy factoring by inspection (y - 3)(y - 9) y = 3 y = 9
I assume the expression is y2+12y+27 as I cannot see the operation symbols between them (editor problem?). If you agree with this then y2 + 12y + 27 = y2 + 9y + 3y + 27 = y(y + 9) + 3(y + 9) = (y + 3)(y + 9)
