x + 19 =1476
x = 1476 - 19
x = 1457
x - 1223 =432
x = 432 + 1223
x = 1655
k mình nha
\(x+19=123x12\)
\(x+19=1476\)
\(x=1476-19=1457\)
\(x-1223=12x36\)
\(x-1223=432\)
\(x=432+1223=1655\)
\(x+19=123\times12\)
\(x+19=1476\)
\(x=1476-19\)
\(x=1457\)
\(x-1223=12\times36\)
\(x-1223=432\)
\(x=432+1223\)
\(x=1655\)
x+19=123×12 x-1223=12×36
x+19=1476 x-1223=432
x =1476 -19 x = 432+1223
x =1457 x =1655
