Answer:

1. x= -1

2. y= 4

Step-by-step explanation:

1. -4x + 7 = 11                              2. 17 = 5y -3

-4x + 7-7= 11 -7                              17 + 3 = 5y -3 +3

-4x = 4                                          20 = 5y

x= 4/-4                                            20/5 = y

x = -1                                              4 = y
