Solving a system of linear equations in two variables PPT, Part 2: Comprehensive ability improvement

12. (Original) Given that x and y are solutions to the quadratic equation system 2x- y=8, @x+4y=7, then the value of x+y is 5.

13. If (m-1)2+√(n+2)=0, then the solution of the equation system mx+2y=n, 5x-ny=2 about x and y is x=1 y=-3/2.

14. Solve the system of equations:

( 1 ){(3( x- 0.1 ) +2( y+0. 2 ) =4, 2"( " x"-" 0"." 1" )" +3"( y+0.2 )" =2 ;
