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:
g(- 4) = - 32
Step-by-step explanation:
substitute x = 4 , g(4) = - 4 into g(x)
4a + b = - 4 → (1)
substitute x = 6 , g(6) = 3 into g(x)
6a + b = 3 → (2)
subtract (1) from (2) term by term to eliminate b
2a + 0 = 3 - (- 4)
2a = 3 + 4 = 7 ( divide both sides by 2 )
a = 3.5
substitute a = 3.5 into (1) and solve for b
4(3.5) + b = - 4
14 + b = - 4 ( subtract 14 from both sides )
b = - 18
Then
g(x) = 3.5x - 18 , so
g(- 4) = 3.5(- 4) - 18 = - 14 - 18 = - 32
