Sagot :
Let's solve the equation:
[tex]\[ -\frac{7}{w-6} = \frac{1}{4w - 24} + 1 \][/tex]
First, let's simplify the right-hand side:
[tex]\[ \frac{1}{4w - 24} + 1 \][/tex]
We can observe that:
[tex]\[ 4w - 24 = 4(w - 6) \][/tex]
Therefore:
[tex]\[ \frac{1}{4w - 24} = \frac{1}{4(w - 6)} \][/tex]
So the original equation becomes:
[tex]\[ -\frac{7}{w-6} = \frac{1}{4(w-6)} + 1 \][/tex]
Next, let's find a common denominator for the terms on the right:
[tex]\[ \frac{1}{4(w-6)} + 1 = \frac{1}{4(w-6)} + \frac{4(w-6)}{4(w-6)} = \frac{1 + 4(w-6)}{4(w-6)} \][/tex]
Simplify the expression:
[tex]\[ \frac{1 + 4w - 24}{4(w-6)} = \frac{1 + 4w - 24}{4(w-6)} = \frac{4w - 23}{4(w-6)} \][/tex]
So the equation becomes:
[tex]\[ -\frac{7}{w-6} = \frac{4w - 23}{4(w-6)} \][/tex]
To clear the denominators, multiply both sides by [tex]\(4(w - 6)\)[/tex]:
[tex]\[ -7 \cdot 4 = 4w - 23 \][/tex]
Simplify and solve for [tex]\(w\)[/tex]:
[tex]\[ -28 = 4w - 23 \][/tex]
Add 23 to both sides:
[tex]\[ -28 + 23 = 4w \][/tex]
[tex]\[ -5 = 4w \][/tex]
Divide both sides by 4:
[tex]\[ w = -\frac{5}{4} \][/tex]
So the solution to the equation is:
[tex]\[ w = -\frac{5}{4} \][/tex]
[tex]\[ \boxed{-\frac{5}{4}} \][/tex]
[tex]\[ -\frac{7}{w-6} = \frac{1}{4w - 24} + 1 \][/tex]
First, let's simplify the right-hand side:
[tex]\[ \frac{1}{4w - 24} + 1 \][/tex]

[tex]\[ 4w - 24 = 4(w - 6) \][/tex]
Therefore:
[tex]\[ \frac{1}{4w - 24} = \frac{1}{4(w - 6)} \][/tex]

Simplify the expression:
[tex]\[ \frac{1 + 4w - 24}{4(w-6)} = \frac{1 + 4w - 24}{4(w-6)} = \frac{4w - 23}{4(w-6)} \][/tex]

[tex]\[ \boxed{-\frac{5}{4}} \][/tex]
