Question

x + y = 1; 2x + 3y = 0.​

Answer 1

Answer:

x=3 y=-2

Step-by-step explanation:

x+y=1.......... (1)

2x+3y=0........(2)

Multiple the (1)equation by 2

2x+2y=2............(3)

Subtract (3)eq. From (2)

2x+3y=0

2x+2y=2

-.... -....... -

y=-2

Put the value of y in (1) eq.

x-2=1

x=3

Answer 2

Answer:

x =1-y ( from first equation )

now put the value of x in second equation

2(1-y)+3y= 0

2 -2y +3y =0

y= -2

now put the value of y in first equation

so ,

x+(-2) = 1

x = 3
