-7.2x < -50.4x + 432

x<10

Step-by-step explanation:

We can start off with adding 50.4x to both sides:

Once we do that we get the following: 43.2x < 432

If you notice, they both are almost the same number with the different of the decimal place. Lets multiply both sides by 10 to get rid of the decimal place:

432x < 4320

Now, if you see, they're basically the same number but the second place is x10 greater.

We can divide both sides by 432 and get x<10 as our answer!
