Select the correct answer.

Which value of [tex]$w$[/tex] makes this equation true?

[tex]\frac{5w + 4}{3} = \frac{3w}{2}[/tex]

A. -8
B. -2
C. -1
D. 8



Answer :

To solve the equation [tex]\( \frac{5v + 4}{3} = \frac{3n}{2} \)[/tex] for a specific value of [tex]\( w \)[/tex], we need to determine the value of [tex]\( w \)[/tex] that can replace both [tex]\( v \)[/tex] and [tex]\( n \)[/tex] and make the equation true.

Let's start by running through the options provided: -8, -2, -1, and 8. We will substitute each value into the equation for both [tex]\( v \)[/tex] and [tex]\( n \)[/tex] and check if the equation holds.

### Step-by-Step Evaluation:

1. Option A: [tex]\( w = -8 \)[/tex]
- Substitute [tex]\( v = -8 \)[/tex] and [tex]\( n = -8 \)[/tex] into the equation:
[tex]\[ \frac{5(-8) + 4}{3} = \frac{3(-8)}{2} \][/tex]
- Simplify both sides:
[tex]\[ \frac{-40 + 4}{3} = \frac{-24}{2} \][/tex]
[tex]\[ \frac{-36}{3} = -12 \][/tex]
[tex]\[ -12 = -12 \quad \text{(True)} \][/tex]
- Therefore, when [tex]\( w = -8 \)[/tex], the equation holds true.

2. Option B: [tex]\( w = -2 \)[/tex]
- Substitute [tex]\( v = -2 \)[/tex] and [tex]\( n = -2 \)[/tex]:
[tex]\[ \frac{5(-2) + 4}{3} = \frac{3(-2)}{2} \][/tex]
- Simplify both sides:
[tex]\[ \frac{-10 + 4}{3} = \frac{-6}{2} \][/tex]
[tex]\[ \frac{-6}{3} = -3 \][/tex]
[tex]\[ -2 \neq -3 \quad \text{(False)} \][/tex]
- Hence, [tex]\( w = -2 \)[/tex] does not satisfy the equation.

3. Option C: [tex]\( w = -1 \)[/tex]
- Substitute [tex]\( v = -1 \)[/tex] and [tex]\( n = -1 \)[/tex]:
[tex]\[ \frac{5(-1) + 4}{3} = \frac{3(-1)}{2} \][/tex]
- Simplify both sides:
[tex]\[ \frac{-5 + 4}{3} = \frac{-3}{2} \][/tex]
[tex]\[ \frac{-1}{3} = -1.5 \quad \text{(False)} \][/tex]
- Hence, [tex]\( w = -1 \)[/tex] does not satisfy the equation.

4. Option D: [tex]\( w = 8 \)[/tex]
- Substitute [tex]\( v = 8 \)[/tex] and [tex]\( n = 8 \)[/tex]:
[tex]\[ \frac{5(8) + 4}{3} = \frac{3(8)}{2} \][/tex]
- Simplify both sides:
[tex]\[ \frac{40 + 4}{3} = \frac{24}{2} \][/tex]
[tex]\[ \frac{44}{3} = 12 \quad \text{(False)} \][/tex]
- Hence, [tex]\( w = 8 \)[/tex] does not satisfy the equation.

### Conclusion:
After evaluating all the options, only [tex]\( w = -8 \)[/tex] makes the equation [tex]\( \frac{5v + 4}{3} = \frac{3n}{2} \)[/tex] true.

Therefore, the correct answer is:
[tex]\[ \boxed{-8} \][/tex]
