解:(1)532-x=196,
532-x+x=196+x,
196+x=532,
196+x-196=532-196,
x=336;
(2)x÷62=438,
x÷62×62=438×62,
x=27156;
(3)74×x=9102,
74×x÷74=9102÷74,
x=23;
(4)x+634=856,
x+634-634=856-634,
x=222.
分析:(1)根據(jù)等式的性質(zhì),兩邊同加上x,得196+x=532,兩邊再同減去196即可;
(2)根據(jù)等式的性質(zhì),兩邊同乘62即可;
(3)根據(jù)等式的性質(zhì),兩邊同除以74即可;
(4)根據(jù)等式的性質(zhì),兩邊同減去634即可.
點評:此題考查了運用等式的性質(zhì)解方程,即等式兩邊同加上或同減去、同乘上或同除以一個數(shù)(0除外),兩邊仍相等,同時注意“=”上下要對齊.
