Question

Помогите пож 1.3(x-0.7)-0.12(x+10)-5x=-9.75

Answer 1

1,3х - 1,3*0,7 - 0,12х - 1,2 - 5х = - 9,75
1,3х - 0,12х - 5х = 0,91 + 1,2 - 9,75
- 3,82х = - 7,64
х = - 7,64 : (- 3,82)
х = 2

Answer 2

(1.3x - 1.3*0.7) - (0.12x + 0.12*10) - 5x = -9.75
1.3x - 0.91 - (0.12x + 1.2) - 5x = -9.75
-3.7x - 0.12x - 0.91 - 1.2 = -9.75
-3.82x = -9.75 + 2.11
-3.82x = -7.64
x = 2
