(8,8x + 4,7) - (5,4x + 2,2) = - 1,6x

Question

(8,8x + 4,7) - (5,4x + 2,2) = - 1,6x

Answer 1

(8,8x + 4,7) - (5,4x + 2,2) = - 1,6x
8,8x + 4,7 - 5,4x - 2,2 = - 1,6x
8,8x +1,6x  - 5,4x = - 4,7+2,2
5x= - 2.5
x= - 2.5/5
х=-0,5

Answer 2

8,8х+4,7-5,4х-2,2=-1,6х; 8,8х-5,4х+1,6х=-4,7+2,2; 3,4х+1,6х=-2,5; 5х=-2,5; х=-0,5 Ответ:-0,5
