Question

X-3/x-4=2 как сделать?

Answer 1

$\frac{x-3}{x-4} = 2$
$x-3 = 2(x-4)$
$x-3 = 2x-8$
$x-2x = 3-8$
$-x = -5$
$x = 5$

Answer 2

To solve the equation $\frac{{X-3}}{{X-4}} = 2$, you can follow these steps:

Step 1: Clear the fraction by multiplying both sides of the equation by $(X-4)$ to eliminate the denominator: $(X-4) \times \frac{{X-3}}{{X-4}} = 2 \times (X-4)$

Step 2: Simplify the left side of the equation: $X - 3 = 2(X-4)$

Step 3: Distribute 2 on the right side of the equation: $X - 3 = 2X - 8$

Step 4: Move all the $X$ terms to one side of the equation and constants to the other side: $X - 2X = -8 + 3$

Step 5: Combine like terms: $-X = -5$

Step 6: Solve for $X$ by multiplying both sides by -1 to isolate $X$: $X = 5$

So, the solution to the equation is $X = 5$.
