[246:(128-x)•10:5-2]•30-12=48

[246:(128-x)•10:5-2]•30=48+12

[246:(128-x)•10:5-2]•30=60

[246:(128-x)•10:5-2]=60:30

[246:(128-x)•10:5-2]=20

246:(128-x)•10:5=20+2

246:(128-x)•10:5=22

246:(128-x)•10=22•5

246:(128-x)•10=110

246:(128-x)=110:10

246:(128-x)=11

128-x=11•246

128-x=2706

x=2706+128

x=2834
