Hello there!
To find the value of n, work to isolate it from all other terms in the equation.
8n+7=31 - Start by subtracting 7 from both sides. 8n + 7 - 7 = 31 - 7
8n = 24 Next, divide both sides by 8 to finish isolating n. 8n÷8 = 24÷8
n = 3
This is your final answer.
I hope this was helpful and have a great rest of your day!

I’m not gonna lie. I’m just answering so I could upload my question
F(x) is y...so when y = 0, x is : -2,1 or 3 only
Answer:

Step-by-step explanation:
We are given that a line has a slope of -2/3 and passes through the point (0,6)
We want to write the equation of this line; there are 3 forms of the line that we can use:
- Slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept
- Standard form, which is ax+by=c, where a, b, and c are free integer coefficients, but a and b cannot be 0, and a cannot be negative
- Slope-point form, which is
, where m is the slope and
is a point
All though while writing the equation of the line in any of these ways is acceptable, the most common way is to write it in slope-intercept form, so let's do it that way.
As we are already given the slope, we can immediately substitute m with that value.
Replace m with -2/3:
y = -2/3x + b
Now we need to find b.
As the equation passes through the point (0, 6), we can use it to help solve for b.
Substitute 0 as x and 6 as y.
6 = -2/3(0) + b
Multiply
6 = 0 + b
Add
6 = b
Substitute 6 as b.
y = -2/3x + 6
