How do you solve the inequality: 3m-3(m+8)> 3m

3(m) - 3(m) + 8 - 3(m) > ?
Repeat this step⬆
3(m) - 3(m) + 8 - 3(m) > 0
-3(m) - 24
First, let's divide ( ÷ ) by the number -3 from each of your sides
Oh and don't forget to flip the inequality sign around
Second, let's subtract ( - ) the number 8 from each of your sides
Finally, we get to your result: -3.0 (-24.0) < ?

Your answer would have to be : m < -8

Hey there!

Functions are basically like machines you put a number into and they give you a new one as an output. This f represents this machine. f(x) represents whatever the output is because it is the x after it has gone through the function machine.

We want to figure out what x is when f(x)=12. Well, we can simply replace f(x) with 12 in the first equation and solve for x!

12=-16x+8

We flip the equation so x is on the left side.

-16x+8=12

We subtract 8 from both sides.

-16x=4

We divide both sides by -16.

x=-1/4

Have a wonderful day! :D
