The answer is:
________________
n = ¼ ; or, write as:
n = 0.25
______________________
Explanation:
__________________
-7 / (2n) = 49 ;
__________________
-49 * (2n) = -7 ;
________________
Divide each side by "(-49)" ; to isolate the "2n" on one side, and to get rid of the "negative" values:
_____________________________
[-49*(2n)] / -49 = -7/ -49 ; to get:
_______________________________
2n = (½); Now, divide EACH side of the equation by "2"; to isolation "n" on one side of the equation, and to solve for: "n";
__________________________________________________
2n / 2 = (½) / 2 ;

Answer:
Step-by-step explanation:
- Mother's age = m
- Son's age = s
<u>3 years later:</u>
- m + 3 = 4(s + 3) ⇒ m = 4s + 12 - 3 = 4s + 9
<u>3 years ago:</u>
- m - 3 = 2(s + 8) ⇒ m = 2s + 18 + 3 = 2s + 21
<u>Solve for s by substitution:</u>
- 4s + 9 = 2s + 21
- 2s = 12
- s = 6
<u>Find the value of m:</u>
Mother is 33 and son is 6

The lengths of segment which is the part of a 12 inch line segment closest to the golden ratio, (1+√5)/2 are 7.4166 inch and 4.5834 inch.
<h3>What is the value of golden ratio?</h3>
The value of golden ratio is equal to 1.618. It can also be given as (1+√5)/2.
A 12 inch line segment is divided into the two parts in a particular ratio. Let suppose the line segment is AC which is divided into AB and BC parts. Thus,
AB+BC=AC
AB+BC=12 ....1
The ratio of both segment is equal to golden ratio. Thus
Put this value in equation one as,
AB+7.4166=12
AB=4.5834
Hence, the lengths of segment which is the part of a 12 inch line segment closest to the golden ratio, (1+√5)/2 are 7.4166 inch and 4.5834 inch.
