Question

i need some help in all of my homework​

Answer 1

Answer:

x=-1,y=-2

Step-by-step explanation:

First,multiply first equation by 3.

6x+3y=-12

5x-3y=1         Now add the equations together because the y's can cancel now

11x=-11    Solve for x

x=-1     Plug in -1 in one of the equations

5(-1) - 3y=1        Solve for y

-3y=6

y=-2

Answer 2

x=-1, y=-2

Step-by-step explanation:

$2x + y = - 4....(1) \\ 5x - 3y = 1....(2) \\ On \: multiplying \: the \: \\ equation \: (1) \: by \: 3 \\ \\ 2x + y = - 4 \times 3 \\ 6x + 3y = - 12....(3) \: On \: adding \: \\ equation \: (3) \: to \: equation \: ( 2) \\ 6x + 5x + 3y - 3y = - 12 + 1 \\ 11x = - 11 \\ x = - 1 \\ put \: the \: value \: of \: x \: equation \: (1) \\ 2 \times - 1 + y = - 4 \\ - 2 + y = - 4 \\ y = - 4 + 2 \\ y = - 2$

I hope this help you
