Answer 1

@k_lynn I have no idea...Would you help them?

Answer 2

you have to solve using the substitution method

Answer 3

Divide each term in the equation by -2
-2y/-2 = 2/-2
then u simplify and cancel the common factors
x=2-y
y=2/-2
x=2-y
y=-1
you are going to have to multiply by -1
x=2-1*-1
y=-1 when u multiply -1*-1 u get 1
x=2+1
y=-1
add the 2+1 =3
so its x=3, y=-1

Answer 4

think that is correct
