`-3/(1-2x)=4/(x-3)`

To solve rational equations, we need to eliminate the denominators. To do so, multiply both sides by the LCD.

`-3/(1-2x)*(1-2x)(x-3)=4/(x-3)*(1-2x)(x-3)`

`-3(x-3)=4(1-2x)`

`-3x+9=4-8x`

Then, combine like terms. So move the terms with x on one side of the equation. While the constants on the other side of the equation.

`-3x + 9 = 4 - 8x`

`+3x - 4` `-4 + 3x`

`------------`

`0 + 5 = 0 - 5x`

`5 = -5x`

And isolate x by dividing both sides by -5.

`5/(-5)=(-5x)/(-5)`

`-1=x`

**Answer: `x =-1` **
