10(7g-9h)-4h-8(-h+8g)
solve for g
7g + 8g since both are positive
15g
solve for h
9h+4h since both are negative
-14h
10-8 since the 8 is negative
12
12(15g-14h)
Since you typed the same equation twice I didn’t know if you meant to , so if it was meant to be doubled it would be
4(30g-28h)

- Midpoint Formula:

Step-by-step explanation:
<u>Step 1: Define</u>
Endpoint A (-2, 1)
Endpoint B (-1, 1)
<u>Step 2: Find Midpoint</u>
Simply plug in your coordinates into the midpoint formula to find midpoint
- Substitute [MF]:

- Subtract/Add:

- Divide:

For step one, it’s Graph A because it’s going through the origin
For step two, the rate of change is -3, you can find the answer by using the rise/run method by going down three and going right once.
For step 3, the dividing method doesn’t work because -1 divided by 2 isn’t 0.
For step four, go to the point (-2,-4) and from that point draw a line up three units. From there draw a line right two units, and you should stop at -1 on the 6-axis
I hope this helped!
To solve for h, you need to isolate/get h by itself in the equation:
s = hp + 2b Subtract 2b on both sides
s - 2b = hp + 2b - 2b
s - 2b = hp Divide p on both sides to get h by itself
