Answer:

See below

Explanation:

9 + 8x
\geq 49

Subtract 9 from both sides

Divide by 8

Answer:

x = 5.

Sorry if you didn't mean find x and I have no idea about the inequality stuff.

Explanation:

We can do a reverse equation in steps. So the first thing we'll do is..

49 - 9 which equals 40.

Then we should do a division since the opposite of multiplication is division.

40 divided by 8 = 5.

To check that we do 5 x 8 = 40 + 9.

Hope that helps. x
