Question

For drawing the graph of 5x + 2y = 16, If x = 2, find the value of y. ​

Answer 1

Solution

$5x + 2y = 16$

$= > 5(2) + 2y = 16$

$= > 10 + 2y = 16$

$by \: transposing$

$= > 16 - 10 = 2y$

$= > 6 = 2y$

$y = \frac{6}{2}$

$= > 3$

$check \: whether$

$5x + 2y = 16$

$= > 5(2) + 2(3) = 16$

$= > 10 + 6 = 16$

Hence verified
