Question

2,4x-5(0,2x+4,2)=0,4x+5,8. (1,5x+3,4):2,5=(4x-5,9):5

Answer 1

2.4x-5(0.2x+4.2)=0.4x+5.8
2.4x-1-21=0.4x+5.8
2.4x-0.4x=5.8+1+21
2x=27.8
x=13.9

(1.5x+3,4):2,5=(4x-5,9):5
0.6x + 1.36=0.8x-1.18
0.6x-0.8x=-1.18-1.36
-0.2x=2.52
x=12.6

Answer 2

2,4х-1х+3=0,4х+5,8

2,4х-1х -0,4х= - 3 + 5,8

1х= 2,8

х=2,8

(1,5х + 3,4) : 2,5 = (4х - 5,9) :5

1.5х - 4х= (- 3,4 - 5.9) :7,5

- 2.5х= - 1,24

х= (-1.24) : (-2.5)

х= 0,496
