Answer:
The answer is z = -2
Step-by-step explanation:
You combine like terms.
Then subtract 7z from both sides.
Add 10 to both sides.
Then divide both sides by -14. (28/-14)
Which then equals to -2
<span>3x + x - 13 + 4 - 6x =12
Combine like terms....
- 2x - 9 =12
Add 9 to both sides....
-2x = 21
Divide both sides by -2 to get x by its self....
x = -21/2</span>

Answer:
28/21
Step-by-step explanation:
You would do y1 - y2 for the numerator which gets you 28. Then you would do x1 - x2 for the denominator which gets you 21. The rate of change is also the slope.
