Answer 1

27х=2626
х=2626/27

6х=48
х=8

22х=220
х=11

112х=68
х=68/112
х=17/28

31х=720
х=720/31

36х=36
х=1

20х=40
х=2

10х=1000
х=100

10х=100
х=10

8х=48
х=6

Answer 2

1) 21x + 6x = 2626 27x = 2626 x = 2626 / 27 x ≈ 97.33

2) 13x - 7x = 48 6x = 48 x = 48 / 6 x = 8

3) 24x - x - x = 220 22x = 220 x = 220 / 22 x = 10

4) 77x + 35x = 68 112x = 68 x = 68 / 112 x ≈ 0.607

5) 25x + 5x + x = 720 31x = 720 x = 720 / 31 x ≈ 23.23

6) 44x - 8x + 6 = 40 36x + 6 = 40 36x = 34 x = 34 / 36 x ≈ 0.944

7) 12x + 8x - 12 = 28 20x - 12 = 28 20x = 40 x = 40 / 20 x = 2

8) 17x - 5x - 2x = 1000 10x = 1000 x = 100

9) 9x + x + 18 = 118 10x + 18 = 118 10x = 100 x = 100 / 10 x = 10

10) 10x - x - x + 6 = 54 8x + 6 = 54 8x = 48 x = 48 / 8 x = 6

Таким образом, решения уравнений: 1) x ≈ 97.33 2) x = 8 3) x = 10 4) x ≈ 0.607 5) x ≈ 23.23 6) x ≈ 0.944 7) x = 2 8) x = 100 9) x = 10 10) x = 6
