Question

to draw graph of 4x + 5y = 19, find y when x = 1

Answer 1

Answer:

$If \: x = 1 \: then \: y = 3$

Step-by-step explanation:

$Given \: Linear\: equation \:in \:two \\variables \: x \:and \:y \:is \: 4x + 5y = 19$

$Substitute \: x = 1 \: in \:the \: equation, \: we\:get$

$\implies 4\times 1 + 5y = 19$

$\implies 4 + 5y = 19$

$\implies 5y = 19 - 4$

$\implies 5y = 15$

$\implies y = \frac{15}{5} = 3$

Therefore.,

$If \: x = 1 \: then \: y = 3$
