Question

3х + х= 20 19 х -17=16х 5 х -3 х= 33

Answer 1

Ответ:

1.

4х=20

х=5

2.

3х=17

3.

2х=33

х=33/2 или 16,5

Answer 2

Ответ:

1) 4х=20

х = 5

2) 19х-16х=17

3х = 17

х= 5 2/3

3) 2х = 33

х = 16,5

Answer 3

3x + x = 20 + 19 4x = 39 x = 39/4

19 + x - 17 = 16x + 5 2 + x = 16x + 5 x - 16x = 5 - 2 -15x = 3 x = -3/15

x + x = 33 2x = 33 x = 33/2

So, the equation does not have a consistent solution for x.
