ANSWER KEY:

1) y =2x + 9

6) y = 2x – 2

11) y =

16) x + 3y = 36

20) a) 0.02x + 0.05y = 2.50

2) y = 5

7) y = –

x – 2

12) –5x + y = 6

17) x = –1

b) 2x + 5y = 250

3) y = –x

8) y = –4

13) 3x + 2y = 16

18) x + 3y = –27

c) y = –

x + 50

4) y =

x + 2

9) y = x + 2

14) –7x + 5y = 35

19) 2x + 3y = 24

5) y = –

10) y = –5x – 4

15) –8x + 5y = –5
