Answer:
$658
Step-by-step explanation:
42 x 99 = 4,158
4,158 - 3,500 = 658
The value of x on the number line is 24 and - 40
A number line in elementary mathematics is a representation of a graduated straight line that acts as an abstraction for real numbers, represented by the letter R. It is assumed that every point on a number line corresponds to a real number, and that every real number corresponds to a point.
When seen as a geometric space, namely the one-dimensional Euclidean space, the number line, also known as a real line in advanced mathematics, is technically defined as the set R of all real numbers. It can be conceptualized as a linear continuum, metric space, topological space, vector space (or affine space), measure space, or topological space.
The given equation is

Solving the equation:

Now we take the two separate values of x:
either x=-8+32 or x=-8-32
or,x=24 or x=-40
The value of x is 24 and - 40.

FG = FE
3n - 4 = n + 8
2n = 12
n = 6
FG = 3(6) - 4
FG = 18 - 4
FG = 14
answer
14
