Answer: 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!! :)

Question 20 points if correct
Vlada [557]

Answer:

B = 155° , C = 25° , D = 155°

Step-by-step explanation:

Given

A = 25°

C = A = 25° [ Vertically Opposite angles ]

Now

A + B = 180°( being linear pair)

25° + B = 180°

B = 180° - 25°

B = 155°

Also

D = B = 155°( vertically opposite angles )
