4n=28n-3 i have to solve for n
Move the letters to one side and the numbers to the other. Change sign when doing so.
4n-28n=-3
Combine terms.
-24n=-3
Multiply everything by -1
24n=3
Now divide both sides by 24
24n/24 = 3/24
n=1/8
I hope this helps.

answered below
y=2x+2
To find the equation of a line, we can use the formula for the slope-intercept form: y = mx + b, where m is the slope of the line and b is the y-intercept.
First, we need to find the slope of the line, which is given by the formula: m = (y2 - y1)/(x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points on the line.
Using the points (2, 6) and (4, 10), we have:
m = (10 - 6)/(4 - 2) = 4/2 = 2
Now that we have the slope, we can substitute it into the equation y = mx + b, along with the coordinates of one of the points. Let's use (2, 6):
6 = 2(2) + b
Simplifying, we get:
6 = 4 + b
To solve for b, we subtract 4 from both sides of the equation:
6 - 4 = b
2 = b
Now we have the y-intercept, b, which is 2. Therefore, the missing piece of information for the equation of the line that passes through the points (2, 6) and (4, 10) is the value 2.
The equation of the line is: y = 2x + 2.
