Răspuns:

a 5*X=123

X=123:5

X= 24,6

5*24,6=123

d 2x+0,234=14,754

2x= 14,754-0,234

2x=14,52

X=14,52 :2

X=7, 26

g 9371,2:X=187,424

X=9371,2:187,424

X=50

b 1,2x+24,3=25,74

.....Nu știu

c X*3,2=23,2

X=23,2:3,2=

X=7,25

e 645,3:X=6,453

X=645,3:6,453

X=100

f 0,07:X=0,0007

X=0,07:0,0007

X=100

h 0,2*X+3,8=4,32

0,2*X=4,32-3,8

0,2*X=0,52

X=0,52:0,2

X=2,6

I 1,2*X+3,8=12,56

1,2*X=12,56-3,8

1,2*X=8,76

X=8,76:1,2

X=7,3
