Question

x-y=-3 , 3x+2y=2 by substitution method ​

Answer 1

Answer:

GIVEN,

x-y= (-3)

3x+2y=2.

$x - y = - 3 \\ y = x + 3 - - - - (1) \\ substitute \: (1) \: in \: 3x + 2y = 2 \\ 3x + 2y = 2 \\ 3x + 2(x + 3) = 2 \\ 3x + 2x + 6 = 2 \\ 5x = 2 - 6 \\ 5x = - 4 \\ x = \frac{ - 4}{5} - - - (2) \\ substitute \: x \: in \: \: \: ( x - y = 3) \: \\ \frac{ - 4}{5} - y = - 3 \\ y = \frac{ - 4}{5} - 3 \\ y = \frac{ - 4 + 15}{5} \\ y = \frac{9}{5}$

Hope it helps you out........
