970 - 10x = 1874
10x = 970 - 1874
10x = (- 904)
x = (-904) : 10
x = (-90,4)
x + x + x + x + ........ + x = 970 - 1874
x + x + x + x + ........ + x = - 904
10x = -904
x = -904 : 10
x = -90,4
vậy x = - 90,4
970 - 10X = 1874
10X = 970 - 1874
10X= -904
X= -904 : 10
X= -90.4
970-x+x+x+..+x=1874
970-10x=1874
10x=970-1874
10x=-904
x=-904:10
x=-90,4
Vậy x=-90,4
=970-10x=1874
10x=970-1874=-904
x=-904:10=-90,4
