Please help with #16, 18, and 20. Sorry that there’s a bunch of other questions in the picture. This is the retake of my previous question which wouldn’t let me edit. I will give brainliest.

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
