Choose the equation that can be used to find the product.

A. [tex]\(\frac{4+1}{x+3}=\frac{1}{9}\)[/tex]

B. [tex]\(4 \times 3 - x\)[/tex]

C. [tex]\(\frac{4 \times 1}{3}=\frac{4}{8}\)[/tex]

D. [tex]\(4 \leadsto 4\)[/tex]



Answer :

Sure, let’s solve the given equation step-by-step:

### Given Equation
[tex]\[ \frac{4+1}{x+3} = \frac{1}{9} \][/tex]

### Step-by-Step Solution

1. Simplify the Numerator:
[tex]\[ 4 + 1 = 5 \][/tex]
This simplifies the equation to:
[tex]\[ \frac{5}{x+3} = \frac{1}{9} \][/tex]

2. Cross-Multiply to Clear the Fraction:
Multiply both sides of the equation by [tex]\((x + 3) \times 9\)[/tex] to eliminate the denominators.
[tex]\[ 5 \times 9 = 1 \times (x + 3) \][/tex]
Simplify:
[tex]\[ 45 = x + 3 \][/tex]

3. Solve for [tex]\( x \)[/tex]:
To isolate [tex]\( x \)[/tex], subtract 3 from both sides.
[tex]\[ 45 - 3 = x \][/tex]
Simplify:
[tex]\[ x = 42 \][/tex]

So, the solution to the equation is:
[tex]\[ x = 42 \][/tex]

Therefore, the product can be found by solving the equation step by step as shown above, and the value of [tex]\( x \)[/tex] is [tex]\( 42 \)[/tex].
