Question

y=-3x+5 and 5x-4y=-3​

Answer 1

Answer:

$y = - 3x + 5$

$5x - 4y = - 3$

$5x - 4( - 3x + 5) = - 3 \\ \: as \: th e \: value \: of \: y = - 3x + 5 \: (given)$

$5x + 12x + 20 = - 3$

$17x = - 3 + 20$

$17x = 17 \\ x = \frac{17}{17 } = 1$

$lets \: put \: x \: in \: 1 \: eq.$

$y = - 3x + 5$

$y = - 3(1) + 5 \\ = - 3 + 5 \\ = 2$

$x = 1 \\ y = 2 \\ hope \: its \: helpful$
