MCQ
To draw graph of $4x+5y=19$, Find y when $x = 1.$
  • A
    $4$
  • ✓
    $3$
  • C
    $2$
  • D
    $-3$
✓

Answer

Correct option: B.
$3$
$\text { Put } x=1 \text { in Eq. } 4 x+5 y=19 $
$4 \times 1+5 y=19 $
$\Rightarrow 5 y=19-4 $
$\Rightarrow 5 y=15 $
$\Rightarrow y=\frac{15}{5}=3$
Hence, option B is correct.
