Question

Solve the followung system of linear equation by subtitution method 3x+2y=-25 , -2x -y=10

Answer 1

Answer:

according to equation

Step-by-step explanation:

$3x + 2y = - 25$

$- 2x -y = 10$

now

= 3x+y=-25

= X=25-2y/3

= -2x-y=10

= -2(25-2y/3)-y=10

= -2(-25y-2y/3)-y=10

= -2(27y/3)=10

= -2(9y)=10

= 9y=10+2

= y=12/9

= y=4/3
