А)3,6х+9,2+1,3х+2,5+9,1х=54,4
3,6х+1,3х+9,1х=54,4-9,2-2,5
14х=42,7
х=42,7:14
х=3,05
проверка
3,6*3,05+9,2+1,3*3,05+
+2,5+9,1*3,05=54,4
10,98+9,2+3,965+2,5+
+27,755=54,4
54,4=54,4
166,4:(89-(7х+76,66))=
=32
166,4:(89-7х-76,66)=32
32*89-32*7х-32*76,66=
=166,4
2848-224х-2453,12=166,4
224х=2848-2453,13-166,4
224х=228,47
х=228,47:224
х=1,02
проверка
166,4:(89-(7*1,02+76,66))=32
