Solve the system of linear equations in two variables by elimination or substitution. y=1 + x
2x+y=-2

x=-1, y=0

Step-by-step explanation:

y=1+x

2x+y=-2

#1 Elimination                             #2 Substitution

y=1+x                                                    y=1+x

2x+y=-2                                                2x+y=-2

-x+y=1                                              2x+(1+x)=-2

2x+y=-2                                           2x+1+x=-2

                                          3x+1=-2

-2x+2y=2                                                  3x=-3

2x+y=-2                                                       x=-1, y=0

3y=0

y=0, x=-1

Hope this helps!! :)
