Answer:

$\huge \boxed{ \boxed{z = 3}}$

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

equation
PEMDAS

<h3>let's solve:</h3>

$\sf simplify \: substraction : \\ \frac{3}{ \frac{z - 2}{z} } = 3z$
$\sf simplify \: complex \: fractio n : \\ \frac{3z}{z - 2} = 3z$
$\sf cross \: multiplication : \\ 3z = 3z(z - 2)$
$\sf divide \: both \: sides \: by \: 3z : \\ \frac{3z}{3z} = \frac{3z(z - 2)}{3z} \\ 1 = z - 2$
$\sf add \: 2 \: to \: bot h \: sides : \\ z - 2 + 2 = 1 + 2 \\ \therefore \: z = 3$

Given g(x)=5x+4, solve for x when g(x)=9

Alex

Answer:

The value of <em>x</em> is equal to 1, written as <em>x</em> = 1.

General Formulas and Concepts:
<u>Algebra I</u>

Equality Properties

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality
Subtraction Property of Equality

Terms/Coefficients

Functions

Function Notation

Step-by-step explanation:

<u>Step 1: Define</u>

g(x) = 5x + 4

g(x) = 9

<u>Step 2: Solve for </u><u><em>x</em></u>

Substitute in function value: 9 = 5x + 4
[Subtraction Property of Equality] Subtract 4 on both sides: 5 = 5x
[Division Property of Equality] Divide 5 on both sides: 1 = x
Rewrite: x = 1

∴ when the function g(x) equals 9, the value of <em>x</em> that makes the function true would be <em>x</em> = 1.
