Question

Помогите СРОЧНО пожалуйста
14 х = 18 – (5 + 12х)

(8х – 17) – (15 + 2х) = - 4х

10– (3х - 16) = (42 + 5х) + (1 – 6х)

1,8х – (х – 1,4) = (0,3х + 1,7) – 0,4

Answer 1

14x=18-5-12x=>26x=13=>x=0.5=1/2

8x-17-15-2x=-4x=>6x-32=-4x=>10x=32=>x=3.2

10-3x+16=42+5x+1-6x=>26-3x=43-x=>2x=-17=>x= -8.5

1.8x-x+1.4=0.3x+1.7-0.4=>0.8x+1.4=0.3x+1.3=>0.5x=-0.1=>x= -0.2
