Solve the inequality:

-15 + 5x > 25

x > 8

Step-by-step explanation:

Hello!

I think I can help.

Inequalities are fairly simply as with most math once you figure out what it is you need to do. In this case we need to subtract and add to get rid of numbers pretty much.

Lets write this out :

-15 + 5x > 25

Now first lets make clear that the goal here is to get rid of all the numbers on the left to get the x on its own so the equation will be :

x > ? and that's it , nothing else.

We can do this by adding and subtracting numbers from the left side, but its important to remember what you do to one side you must do to the other.

So lets get rid of the number without the x first which would be -15. Now to get rid of -15 you need to add +15 so you can get that number to 0 and it will be gone. But remember adding 15 to -15 means we have to add 15 to 25 as well since we need to do what we do on one side to the other.

So:

-15 + 5x > 25

+15          +15

So now we have :

0 + 5x > 40

We can toss the 0 cause it has no value :

5x > 40

Alright now we have the 5 to get rid of which is attached to x which sucks.

Now since this is 5 multiplied by x we need to do the opposite to get rid of it. Which means it is division we have to do.

Now what we will do here is make the 5 into a 1 since 1x is the same as just x on its own cause x believe it or not has a value of 1.

So to get this 1 we can actually divide the number (5) by itself (5) to get 1.

Cause a number divided by itself is 1.

BUT always remember that what you do to one side you MUST do to the other.

So:

5x > 40

/5    /5

5x/5 = 1x or just x > 40/5 = 8

It would now be :

x > 8

Which is a true statement and is your answer!

I hope this helped you!
