how do you solve this inequality?

Question

y - 7 > 3 + 2y


i got -1y>10?

Answer 1

y - 7 > 3 + 2y
- y > 10
y < -10

You need to solve for y likely. When you change the signs, you need to change the direction of the inequality.

Answer 2

Actually, you can avoid the sign-reversing multiplication be -1 by keeping the coeeficient of y positive.

y - 7 > 3 + 2y
subtract y from both sides:
-7 > 3 + y
subtract 3 from both sides:
-10 > y, or y < -10

Answer 3

Hey there!

Here's the answer.

y-7>3+2y --> Write the problem.
-y-7>3 --> Subtract 2y on both sides of the inequality.
-y>10 --> Add 7 on both sides of the inequality.
y<-10 Divide both sides of the inequality by -1 and reverse the inequality sign.

So the answer is y<-10.

Hope it helps!

Answer 4

y - 7 > 3 + 2y
subtract y from both sides

-7 > 3 + y
subtract 3 from both sides

-10 > y or

y > -10

Answer 5

y - 7 > 3 + 2y
y - 2y > 3 + 7
- y > 10
y > - 10

Answer: y > - 10

Answer 6

get the y's on the same side
so from here
y - 7 > 3 + 2y
add 7 to both sides to get
y > 3 + 7 + 2y
than subtract 2y on both sides
-y > 10
now you need to get rid of the negative
multiply both sides by -1
whenever you multiply both sides by a negative
the sign changes, so < becomes > or > becomes <
so your final answer is
y < -10

Answer 7

y-7>3+2y
-y>10
y<-10 ANs.

Answer 8

You're answer is right, but you're not finished. You haven't solved for y yet. Now multiply by -1 on both sides (to get rid of the neg.) That gives you y < -10. (Don't forget to switch the inequality when you divide or multiply by a negative)

Answer 9

y - 7 > 3 + 2y
first add 7 to both sides of the equation. This gives you:
y > 10 + 2y
Next subtract 2y from both sides. This gives you:
-y > 10
Next you multiply both side by -1. This gives you the answer:
y > -10

Answer 10

y - 7 > 3 + 2y
- y > 10
y < -10

this things are very easy to do...you should try to concentrate more and you'll enjoy doing them...for real
