Solving the Equation: (2+x)(x-7)/(x-5)(x+4) = 1
The given equation is a rational expression, and we need to find the values of x that satisfy the equation. Let's start by simplifying the equation.
(2+x)(x-7)/(x-5)(x+4) = 1
To simplify the equation, we can start by multiplying the numerators and denominators separately.
(2x - 14 + x^2 - 7x)/(x^2 - x - 20) = 1
Now, we can cross-multiply to eliminate the fractions.
x^2 - 7x - 14 = x^2 - x - 20
Let's simplify the equation further by combining like terms.
-7x - 14 = -x - 20
-6x = -6
x = 1
Therefore, the value of x that satisfies the equation is x = 1.
Checking the Solution
Let's plug in x = 1 back into the original equation to verify our solution.
(2+1)(1-7)/(1-5)(1+4) = ?
(3)(-6)/(-4)(5) = ?
18/20 = 9/10 = 1
The solution checks out, and we have confirmed that the value of x that satisfies the equation is indeed x = 1.
