MCQ
The root of the equation $\text{3x}=\frac{20}{7}-\text{x}$ is:
  • A
    $\text{10}$
  • B
    $\frac{20}{7}$
  • C
    $-\frac{5}{7}$
  • ✓
    $\frac{5}{7}$
✓

Answer

Correct option: D.
$\frac{5}{7}$
$\text{3x}= \frac{20}{7}- \text{x}$
$\Rightarrow \text{3x + x} = \frac{20}{7}$
$\text{4x}= \frac{20}{7}$
$\Rightarrow\text{x} = \frac{20}{7\times4}=\frac{5}{7}$
