So the specialized households actually produced tons of wheat X( 1+ 12%) and corn (18-x) (1+10%) last year.
X( 1+ 12%)+( 18-X)( 1+ 10%)= 20
X= 10
X (1+12%) =11.2 tons.
(18-x) (1+10%) = 8.8 tons.
A: Last year, this specialized household actually produced 1 1.2 tons of wheat and 8.8 tons of corn.
I wish you progress in your studies and go up a storey still higher! (*^__^*)
