The answer would be 32.064
Given:
4x + 7 = 23
Let's solve for x.
First Step:
Subtract 7 from both sides
4x + 7 - 7 = 23 - 7
4x = 16
Next Step:
DIvide both sides by 4

ANSWER:
x = 4
Answer:
- asymptotes: x = -4, x = 4
- zeros: x = 0
Step-by-step explanation:
The vertical asymptotes of the rational expression are the places where the denominator is zero:
x^2 -16 = 0
(x -4)(x +4) = 0 . . . . . true for x=4, x=-4
x = 4, x = -4 are the equations of the vertical asymptotes
__
The zeros of a rational expression are the places where the numerator is zero:
4x = 0
x = 0 . . . . . . divide by 4
