Question

(y=-3x)-----------
(x+y=4)

Answer 1

Answer:
`x=-2 , y = 6`

Step-by-step explanation: Use substitution to solve this system because the x value for y is given. Plug it into the second equation.

`x+(-3x) = 4`

Then add like terms,

`-2x = 4`

Which means,

`x=-2`

Plug it into the first equation to solve for y

`y= -3(-2)`

Which means,

`y=6`
