Вариант 1. Реши уравнения: a) x + 125=230 + 25; б) a – 37= 54; в) b × 36 = 72 × 16; г) 1836 : (x – 26) = 18

a) x + 125 = 230 + 25

x + 125 = 255

x = 255 - 125

x = 130

б) a - 37 = 54

a = 54 + 37

a = 91

в) b × 36 = 72 × 16

b × 36 = 1152

b = 1152 : 36

b = 32

г) 1836 : (x – 26) = 18

x - 26 = 1836 : 18

x - 26 = 102

x = 102 + 26

x = 128
