Answer:
x = -5.25 or 21/4
Step-by-step explanation:
When break the bracket out, if there is a minus sign in front of the bracket, when we break it out, the sign inside the bracket would become positive:
67 = 18 - (8x - 7)
67 = 18 - 8x - (-7)
67 = 18 - 8x + 7
67 = 18 + 7 - 8x
67 = 25 - 8x or rewrite for easier look: 25 - 8x = 67
25 - 8x = 67
8x = 25 - 67
8x = -42
Divide both side by 8, we got:
x = -42 / 8
x = -5.25 or 21/4

Answer:
The equation for the following graph:
Step-by-step explanation:
- You first need to find the slope by using the <u>slope formula</u>:
(where 
is the first point and 
is the second point)
-Use the given points 
and 
from the graph for the formula:
Then, you solve:
After you have found the slope, use the slope 
and the first point for the <u>point-slope formula:</u>
<u>(</u>where 
is the slope and 
is the first point)
Then, you solve:
So, the equation for the following graph is .
