Question

the value of x which satisfies the equation
x/2-x/4=x-9​

Answer 1

$\frac{x}{2} - \frac{x}{4} = x - 9 \\ \frac{x}{2} - \frac{x}{4} - x = - 9\\ \frac{2x - x - 4x }{4} = - 9 \\ \frac{ - 3x}{4} = - 9 \\ - 3x = 4 \times ( - 9) \\ - 3x = - 36 \\ x = \frac{ - 36}{ - 3} \\ x = 12$

If we put x = 12 , then it satisfies the equation.
