Answer 1

Respuesta:

1) X +1 = 2: X=1

2) X + 1 = 0: X=-1

3) X +2 = 1: X=-1

4) X – 2 = 1: X=3

5) X – 2 = 0: X=2

6) X + 1 = - 2: X=-3

7) X – 1 = - 2: X=-1

8) 2X = 4: X=2

9) 3X = - 6: X=-2

10) 2x – x + 4 + 2 = 8: X=2

11) 3x + 1 – 2x = 9 – 3 3) 6 + 2x – 4 = x – 1: ?

12) – 6 – 2x = - 3x – 6 5) x + x +4 +2 = 8: ?

13) 2x + x +5 – 5 = 6: X=2

14) 2x – x – 3 – 5 = 2: X=10

15) 2x + 2 – 1 – x = 2: X=1

16) 5x – 4= 3x – 2: X=1

17) 2x – 5 +1 +x = + x – 6: X=-1

18) – 2x – 5 = 6 – x – 2: X=-9

19) – 10 – 4 x + 2 = x – 3 – 4x: X= - 1/5

20) – 9x – 6 + 4 = 4 + 2x – 8x​: X=-2
