Answer:

1)  f=−8/7 2) z=−3/7

Step-by-step explanation:

1)-f+8=-8f

−f+8=−8f

Step 1: Add 8f to both sides.

−f+8+8f=−8f+8f

7f+8=0

Step 2: Subtract 8 from both sides.

7f+8−8=0−8

7f=−8

Step 3: Divide both sides by 7.

7f/7=−8/7

f=-8/7

2) 6z-5=-z-8

6z−5=−z−8

Step 1: Add z to both sides.

6z−5+z=−z−8+z

7z−5=−8

Step 2: Add 5 to both sides.

7z−5+5=−8+5

7z=−3

Step 3: Divide both sides by 7.

7z/7=−3/7
