Justify each step by identifying the property used:

1/2(y+3)1/3(4-y)
3(y+3)2(4-y)
3y+98-2y
5y+98
5y-1
y-0.2

This is not very clear. what is the original problem?

anonymous · Answer

1/2 (y+3) > 1/3 (4-y) is the original inequality to start with.

anonymous · Answer

You need to first get rid of denominator. ask yourself, what is the LCD of denominator over all, ie, what is LCD(2,3)?

anonymous · Answer

My teacher wants us to justify each step by identifying the property used

anonymous · Answer

did the second setp "3(y+3)>2(4-y)"? Did you see the denominator disapear?

anonymous · Answer

yes that's the second step, but i don't know what property they used to get rid of the denominators

anonymous · Answer

Multiply LCD on both sides of inequalies to remove the fractions
