Solve for z: 2+8-z=-24 show your work solve: 20% of =100 show your work

The first answer is 34. You just need to add 8 and 2 on one side. Then, add 24 to both sides to cancel out the -24 on the opposite side. At the same time, add z to both sides to cancel out the negative. That would lead z to equal 34.

The second question is 500. This is because 20% is 1/5 of 100%. If you multiply the 100 by 5 times, you get the 100% of that question.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
