1) у=14 х+16

2) у=8 х+3

3) у=5 х+8

4) у=5 х+4

5) у=-14 х+16

6) у=2 х-9

Помогите!

(2) y=14x+16

14x+16=0

14x+16

x=16:14

x=8/7

(3) y=8x+3

8x+3=0

8x+3

x=3:8

x = 3/8

(4) y=5x+8

5x+8=0

5x+8

x=8:5

x=1.6

(5) y=5x+4

5x+4=0

5x+4=0

x=4:5

= 0.8

(6) y=2x-9

2x-9=0

2x-9

x=9:2

x=4.5

(7) y = - 14x+16

-14x+16=0

-14x+16

-x=16:14

-x=8/7

x = 8/7
