Solve the inequality 3k > 5k+12

Natali5045456 [20]

Alright, let's solve this problem! :)

First we need to subtract 5k from both sides.

3k−5k>12

Then we simplify 3k - 5k to -2k.

-2k > 12

Now we divide both sides by -2.

k < -12/2

Now we simplify 12/2 to 6.

k < -6

✔️Done!

Have an amazing day!

seeing that x is on the tens place which is the second last place and y is on the ones place meaning it has to be the last value.
