a) 136 - x : 48 = 27 + 92
136 - x : 48 = 119
x : 48 = 136 - 119
x : 48 = 17
x = 17 x 48
x = 816
b) 43,7 - x - 8,92 = 0,348 x 19
43,7 - x - 8,92 = 6,612
43,7 - x = 6,612 + 8,92
43,7 - x = 15,532
x = 43,7 - 15,532
x = 28,168
\(136-x:48=27+92\)
\(136-x:48=119\)
\(x:48=136-119\)
\(x:48=17\)
\(x=17\times48\)
\(x=816\)
\(43,7-x-8,92=0,348\times19\)
\(34,78-x=6,612\)
\(x=34,78-6,612\)
\(x=28,168\)
