Question

Реши уравнения.x – 8 = 116+ х = 2018 - х = 6​

Answer 1

х - 8 = 11

х = 11 + 8

х = 19

________________

6 + х = 20

х = 20 - 6

х = 14

________________

18 - х = 6

х = 18 - 6

х = 12

Answer 2

1) х-8=11

х=11+8

х=19

2)6+х=20

х=20-6

х=14

3) 18-х=6

-х=6-18

-х=-12

х=-12:(-1)

х=12
