Question 262683
The given equations are,
                   -0.9x+0.8y=14.6  ...(1)
                   -0.3x+0.1y=3.7   ...(2)
(2)*3=>            -0.9x+0.3y = 11.1 ..(3)  
(1)-(3)=>           0.8y-0.3y = 14.6-11.1
                    0.5y = 3.5
                    y = 3.5/0.5
                    y = 7
(1)=>               -0.9x+0.8*7 = 14.6
                    -0.9x = 14.6-5.6
                    -0.9x = 9
                    x = 9/(-0.9)
                    x = -10 
Therefore the solution is x= -10 and y = 7
