x-y=8. 3x-3y=16 by table method |
| Answer» x - y = 8.................(1)3 x - 3 y = 16.............(2)Here,\xa0{tex}a _ { 1 } = 1 , b _ { 1 } = - 1 , c _ { 1 } = - 8{/tex}{tex}a _ { 2 } = 3 , b _ { 2 } = - 3 , c _ { 2 } = - 16{/tex}We see that\xa0{tex}\\frac { a _ { 1 } } { a _ { 2 } } = \\frac { b _ { 1 } } { b _ { 2 } } \\neq \\frac { c _ { 1 } } { c _ { 2 } }{/tex}Hence, the lines represented by the equations(1) and (2) are parallel.Therefore, equations (1) and ( 2 ) have no solution, i.e., the given pair of linear equation is inconsistent. | |
