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!! :)

Over [174]

Answer:

82

Step-by-step explanation:

f(x) = 5x - 3

g(x) = 2x + 9

f(g(x)) = 5 (2x + 9) - 3 ..... replace x with g(x)

f(g(4)) = 5 * (2 * 4 + 9) -3 = 85 - 3 = 82

Based on that we see that a is 9
