Question

Решите уравнение:
Г) 256m-147m-1871=63747
Д) 88880:110+x=809
Е) 6871+p : 121=7000
Ж)3810+1206:y=3877
З) k+12705:121=105

Answer 1

$256m - 147m - 1871 = 63747 \\ 109m - 1871 = 63747 \\ 109m = 63747 + 1871 \\ 109m = 65618 \\ m = 65618 \div 109 \\ m = 602$

$88880 \div 110 + x = 809 \\ 808 + x = 809 \\ x = 809 - 808 \\ x = 1$

$6871 + p \div 121 = 7000 \\ p \div 121 = 7000 - 6871 \\ p \div 121 = 129 \\ p = 121 \times 129 \\ p = 15609$

$3810 + 1206 \div y = 3877 \\ 1206 \div y = 3877 - 3810 \\ 1206 \div y = 67 \\ y = 1206 \div 67 \\ y =18$

$k + 12705 \div 121 = 105 \\ k + 105 = 105 \\ k = 105 - 105 \\ k = 0$
