Question

Решите уравнение:
13(х-13)+14(14х-2)=11(3х-11)+28+(10х-21)

Answer 1

13х-169+196х-28=33х-121+28+10х-21
13х+196х-33х-10х=-121+28-21+169+28
166х=83
х=83/166
х=0,5

Answer 2

13(х-13)+14(14х-2)=11(3х-11)+28+(10х-21)
13х-169+196х-28=33х-121+28+10х-21
209х-197=43х-114
209х-43х= -114+197
166х=83
х=83:16
х=0.5
