Question

2 - (0,9x - 1,3) = 1,3x

3. - (3,3x + 1,2) - (0,7x + 1,6) = 0

4. - (4,1x + 2,5) - (2,3x + 3,9) = 1,6x

5. (3,6x + 2,5) - (1,8x + 2,3) = 1,6x

Решите плизз

Answer 1

1)2-(0,9x-1,3)=1,3х
3.3=1,3х+0,9х
2.2х=3.3
х=3.3/2.2
х=1.5

Answer 2

3,3х-0,7х=1,6+1,2

Answer 3

4х=2,8

Answer 4

х=2,8/-4

Answer 5

х=-0,7

Answer 6
