The LCM is 45x3
Not sure which you mean, take your pick: (8y)3+27=(8y+3)((8y)2-3*(8y)+9)=(8y+3)(64y2-24y+9); or 8y3+27=(2y+3)(4y2-6y+9)
4y + 8y = 12y 4y - 8y = -4y 4y x 8y = 32y2 4y/8y = 1/2
16y^2(8y)=0? Factor out an 8y to give you 8y(2y(2))=0 Use order of operations to give you 8y(4y)=0 Distribute to give you 32y=0 and ultimately the answer will be 0 If there is a missing plus or minus operator between 16y2 and the 8y, then it can be factorised by taking out common factors: 16y2 ± 8y = 0 ⇒ 8y(2y ± 1) = 0

You can only simplify, and by the way you wrote it, it is a bit confusing. I'll assume you mean: 8y + 2 - 18y -5. In order to do this you must combine like terms, or the same things. We can combine 8y and -18y, as they are both y. 8y - 18y = -10y. Now we can combine 2 and -5, as they both are plain. 2 - 5 = -3. Your final answer would be: -10y - 3.
-8y+9=18y-4Add 8y to both sides.9=26y-4Add 4 to both sides.13=26yDivide 13 by 26.1/2=y or 0.5=y
LCM(12x, 8y) = 24xy.
10y + 8y = 18y = 15 y = 15/18 y = 5/6 = 0.833333.....
