Решите уравнение (80 + 16*(4х + 154)): 48= 55

(80 + 16(4х + 154)) = 55 * 48
(80 + 16(4х + 154)) = 2640
16(4х + 154) = 2640 - 80
16(4х + 154) = 2560
4х + 154 = 2560 : 16
4х + 154 = 160
4х  = 160 - 154
4х = 6
 x = 1 1/2
 x = 1,5
 

(80+16*(4х+154)):48=55
80+16(4х+154)=55*48
80+16(4х+154)=2640
16(4х+154)=2640-80
16(4х+154)=2560
4х+154=2560:16
4х+154=160
4х=160-154
4х=6
х=6:4
х=1,5(или х =)
ответ: х = 1,5
