Answer 1

X+2, 762=3
x=3-2,762
x=0,238

9, 3-x=7, 193
x=9-7,193
x=1,807

X-28, 43=0, 147
x=0,147+28,43
x=28,577

X·0, 8=5, 6
x=5,6:0,8
x=7

1, 2·x=0, 144
x=1,2:0,144
x=8,(3)

X:2, 3=0, 13
x=0,13*2,3
x=0,299

6, 25:x=2, 5
x=6,25:2,5
x=2,5

3x+2, 32=x+11, 8
3x-x=11,8-2,32
2x=9,48
x=9,48:2
x=4,74

2x-21, 135=x-18, 68
2x-x=21,135-18,68
x=2,455

4, 8-3x=0, 3
3x=4,8-0,3
3x=4,5
x=4,5:3
x=1,5

X·13,27=15, 924
x=15,924:13,27
x=1,2

X:12 , 3=0, 04
x=0,04*12,3
x=0,492
