Answer:
1) Add 3n to both sides
2) Subtract 5 from both sides
3) Divide both sides by 6
n=3
Step-by-step explanation:
3n+5=23-3n
+3n +3n
6n+5=23
-5 -5
6n=18
/6 /6
n=3
Answer:
1/5 × 950
(2nd option)
Step-by-step explanation:

So 20% of 950 = 1/5 × 950
If the note paper is a square, the answer would be 156.25cm^2
Answer: (0,3) and (2,2)
There are infinitely many possible answers.
======================================================
Explanation:
If we plug in x = 0 and solve for y, then we get,
x+2y = 6
0+2y = 6
2y = 6
y = 6/2
y = 3
So x = 0 and y = 3 pair up together. We get the ordered pair (x,y) = (0,3)
This is one point on the line.
------------------------
Pick any other value you want for x. Let's say we go for x = 2
x+2y = 6
2+2y = 6
2y = 6-2
2y = 4
y = 4/2
y = 2
The point (x,y) = (2,2) is also on the line, and also another solution.
------------------------
One last example. Let's plug in x = 4
x+2y = 6
4+2y = 6
2y = 6-4
2y = 2
y = 2/2
y = 1
The point (x,y) = (4,1) is another solution.
