Question

Solve the inequality 3x + 4y > 12 for y. Do not graph... if you give me thwe anwser I'll give you a metal

Answer 1

Ready to work on this together?

Answer 2

I dont know how to do it

Answer 3

3x+4y>12
divide by 3
x+4y>4
divide by 4
x+y>1
thats as close as you can get...

Answer 4

Whoops, sorry. Got stuck on another problem.

So, as iharrell explained you can get it down to x+y>1. However, since you need to solve for y (according to the problem; usually his answer would also be acceptable), you subtract both sides by x and you are left with


y > 1 + x

Answer 5

Oh wait, I did see a typo though, so lemme start from scratch.

Answer 6

Solve the inequality 3x + 4y > 12 for y.

3x + 4y > 12

Subtract by 3x on both sides to get:

4y > -3x + 12

Divide by 4 to get the y by itself:

y > - (3/4)x + 3

And there ya go! If you were to graph it, you'd shade everything above and to the left of the line.
