Question

1,2-2*(1,3x+1)=5,6-27,04 8*(2a-6)=2*(4a+3) помогите решить

Answer 1

1,2-2*(1,3х+1)=5,6-27,04
1,2-2,6х-2=-21,44
2,6х=1,2-2+21,44
2,6х=20,64
х=20,64:2,6
х=7,93
1,2-2*(1,3*7,93+1)=5,6-27,04
1,2-2*11,3=-21,44
1,2-22,6=-21,44
-21,4=-21,4
8*(2а-6)=2*(4а+3)
16а-48=8а+6
16а-8а=6+48
8а=54
а=54:8
а=6,75
8*(2*6,75-6)=2*(4*6,75+3)
8*7,5=2*30
60=60
