8y^3+316
divide both sides by 4 (smallest divisable number) just say you tried to factor 2 and 3 and they weren't whole numbers and then you tried 4 and gave you the answer :)
4(2y^3+79)
Please don't post masses of questions all at once. 1-2 problems per post would be more realistic and fairer to others who need help.
Regarding <span>x-2/5 = 1/5
We are to solve for x. To do this, let's remove the fractions by mult. all 3 terms by 5. Then 5x - 2 = 1, or 5x = 3.
Dividing both sides by x, we get x = 3/5 (answer). Check this by subst. 3/5 into the original equation.</span>
