To draw graph of 4x + 5y = 19, Find y when x = 1.
विकल्प
4
3
2
-3
उत्तर
3
Explanation:
4x + 5y = 19
When x = 1, then y will be
\[4\left( 1 \right) + 5y = 19\]
\[ \Rightarrow 4 + 5y = 19\]
\[ \Rightarrow 5y = 19 - 4 = 15\]
\[ \Rightarrow 5y = 15\]
\[ \Rightarrow y = \frac{15}{5} = 3\]
Hence, the correct answer is 3.
