Answer 1

a, x+2,1=5,6
x=5,6-2,1=3,5
b.3,7+x=11,7
x=11,7-3,7=8
c.x-7,2=9,18
x=9,18+7,2=16,38
d.8-x=3,723
x=8-3,723=4,227
e. 4,3+x+3,42=7,8
4,3+x=7,8-3,42
4,3+x=4,38
x=4,38-4,3=0,08
f.x-(25,7-3,41)=7,71
x-22,9=7,71
x=7,71+22,9=30
g.x-4,5=9
x=9+4,5=13,5
h. 10,3x=573,71
x=573,71:10,3=59,36
I 7x=84,07
x=84,07:7=12,01
j. x2.9=3,5, x=3,5:2,9=1,2
k. 20:x=6,4
x=20:6,4=3,125
