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

Sagot :

To determine the value of [tex]\( w \)[/tex] that satisfies the equation

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

we will solve the equation step by step.

1. Clear the denominators by finding a common multiple:
The common multiple of 3 and 2 is 6. Multiply both sides of the equation by 6 to eliminate the fractions:

[tex]\[ 6 \cdot \frac{5w + 4}{3} = 6 \cdot \frac{3w}{2}. \][/tex]

2. Simplify both sides:

[tex]\[ 6 \cdot \frac{5w + 4}{3} = 2 \cdot (5w + 4) = 10w + 8, \][/tex]

and

[tex]\[ 6 \cdot \frac{3w}{2} = 3 \cdot (3w) = 9w. \][/tex]

So, the equation becomes:

[tex]\[ 10w + 8 = 9w. \][/tex]

3. Isolate the variable [tex]\( w \)[/tex]:

Subtract [tex]\( 9w \)[/tex] from both sides to isolate [tex]\( w \)[/tex] on one side of the equation:

[tex]\[ 10w + 8 - 9w = 9w - 9w, \][/tex]

which simplifies to:

[tex]\[ w + 8 = 0. \][/tex]

4. Solve for [tex]\( w \)[/tex]:

Subtract 8 from both sides:

[tex]\[ w = -8. \][/tex]

Hence, the value of [tex]\( w \)[/tex] that makes the equation true is [tex]\(-8\)[/tex].

Therefore, the correct answer is:

[tex]\[ \boxed{-8} \][/tex]
