Therefore by given conditions,
4x + ( )y + 2( ) = ( )
x + 2y + ( )( ) = ( )
( )x + 2y + 3z = ( )
Matrix form of above equations is,
`[("( )", 3, "( )"),(1, "( )", 3),("( )", 2, "( )")] [(x),(y),(z)] =[("( )"), (45), ("( )")]`
R_{1} ↔ R_{2}
`[(1, 2, 3),("( )", "( )", "( )"),(6, 2, 3)] [(x),(y),(z)] =[("( )"), (60), ("( )")]`
R_{2} – 4R_{1}, R_{3} – 6R_{1}
`[(1, 2, 3),("( )", -5, "( )"),(0, "( )", -15)] [(x),(y),(z)] =[(45), ("( )"), (-200)]`
`(-1)/5 "R"_2, (-1)/5 "R"_3`
`[("( )", 2, 3),(0, "( )", 2),(0, 2, "( )")] [(x),("( )"),(z)] =[(45), (24), (40)]`
R_{3} – 2R_{2}
`[(1, 2, 3),(0, 1, 2),(0, 0, -1)] [(x),(y),(z)] =[("( )"), ("( )"), ("( )")]`
By pre multiplying we get,
x + 2y + ( )z = ( ) .....(i)
y + 2z = 24 ......(ii)
–z = ( ) ......(iii)
From (iii), we get, z = ( )
From (ii), we get, y = ( )
From (i), we get, x = ( )
