-3y+12=6 what the inequality for y

Question

Solve the inequaluty for y

Answer 1

 

This is an equation ... not an inequality

 

-3y + 12 = 6

 

-3y = 6 - 12

 

-3y = -6

 

y - -6/(-3)

 

y = 2

 

If this were -3y + 12 > 12

                   You would need to reverse the direction of the inequality when dividing both sides by a negative.

                   y < 2

 

If this were -3y + 12 < 12 

                   y > 2 ... (for same reason above)
