The practical problems of "master's study plan" and the answers and processes in the second class of mathematical linear equation.
Solution: If a professional household planned to produce x tons of wheat last year, it would produce 18-X tons of corn.

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.
