Question

3x + 2y+ 25 = 0 ; 2x+ y + 10 give me full solution ​

Answer 1

$3x + 2y + 25 = 0 .... < 1 > \\ \\ 2x + y + 10 = 0.... < 2 > \\ \\ now \: in \: 1 \\ \\ 4x + 2y + 25 - x = 0 \\ \\ 2(2x + y) + 25 - x = 0 \\ \\ from \: 2 \\ \\ 2( - 10) + 25 - x = 0 \\ \\ 5 - x = 0 \\ \\ x = 5 \\ \\ y = - 20 \: from \: 2$

hope it helps

Answer 2

3x + 2y + 25 = 0-------------1

2x + y + 10 = 0---------------2

Multiply second equation by 2

3x + 2y + 25 = 0》3x + 2y = -25

4x + 2y + 20 = 0》4x + 2y = -20

- - +

- x + 0 = -5

× = 5

y = - 20
