Question

Реши уравнение x+24=35+45 , 80-b=20-8, c-12= 63+14

Answer 1

Х + 24 = 35 + 45
х + 24 = 80
х = 80 - 24
х = 56

80 - b = 20 - 8
80 - b = 12
b = 80 -12
b = 68

с - 12 = 63  + 14
с - 12 = 77
с = 77 + 12
с = 89

Answer 2

Х+24=35+45        80-b=20-8        c-12=63+14       
х+24=80              80-b=12            c-12=77
х=80-24               b=80-12            c=77+12
х=56                    b=68                  c=89
56+24=35+45     80-68=20-8       89-12=63+14
