Solve $\frac{\text{x}-1}{3}=\frac{\text{x}-2}{4}$:
  • A

  • B
    $2$
  • C
    $10$
  • ✓
    $-10$
✓

Answer

Correct option: D.
$-10$

 $\frac{\text{x}-1}{3}=\frac{\text{x}-2}{4}$
$\Rightarrow 4(x + 1) = 3(x - 1)$
$\Rightarrow 4x + 4 = 3x - 6$
$\Rightarrow 4x - 3x = -6 - 4$
$\Rightarrow x = -10$
