Question

1) X+85,21=-11,4
2)113,4-X=120
3)X-25,9=11,352

Answer 1

1) x=-11, 4-85, 21
x= -11, 4+ (-85, 21)
x= -96, 61.
2) 113,4 - x = 120
x= 113,4-120
x= -6,6
3) x-25, 9=11,352
x= 11, 352 + 25, 9
x= 37, 252.

Answer 2

1) х+85,21=-11,4
х=-11,4-85,21
х=-96,61
2)113,4-х=120
х=113,4-120
х=-6,6
3)х-25.9= 11,352
х= 25,9+11,352
х=37,252
