Question

Solve 4x−9y=13 for y.

Answer 1

Answer:

$y = - \frac{13}{9} + \frac{4}{9} x$

Step-by-step explanation:

$4x - 9y = 13$

$4x - 9y - 4x = 13 - 4x$

$- 9y = 13 - 4x$

$y = 9y \div (9) = (13 - 4x) \div ( - 9)$

$y = (13 - 4x) \div( - 9)$

$y = 13 \div ( - 9) - 4x \div ( - 9)$

$y = - 13 \div 9 - 4x \div ( - 9)$

$y = - \frac{13}{9} - 4x \div ( - 9)$

$y = - \frac{13}{9} + 4x \div 9$

$\boxed{\green{y = - \frac{13}{9} + \frac{4}{9} x, x E R}}$
