Question

Please help me.

I don't understand how to solve inequalities like this.

1.) −2y−7>11

2.) 2x+1≥5 or -3x > -9

Answer 1

It is just like solving an equation.

Answer 2

So you are still trying to get the variable by itself @Guez

Answer 3

-2y-7= 11 @Guez would you know what ot do here?

Answer 4

to do when the problem has an equal sign

Answer 5

Add 7 to both sides?

Answer 6

Right.

Answer 7

-2y = 18

Answer 8

y = 9?

Answer 9

Then you know we would have to divide and get -9
However the original problem would say

-2y > 18
When you divide by a negative you must flip that sign
y < -9

Answer 10

I'm sorry negative 9 = -9

Answer 11

Okay, now some of the questions have a sub-question that asks,"Describe the graph of the solution". What do I do then?

Answer 12

Oh okay

Answer 13

What I mean is when I have the solution, it asks to describe the graph of the solution.

Answer 14

y < -9
