Answer» Answer 13x+11y=7011x+13y=74Multiplying EQN(1) with 1111(13x+11y)=11×70⟹143x+121y=770−−−eqn(3)Multiplying eqn(2) with 1313(11x+13y)=13×74143x+169y=962Subtracting eqn(3) from eqn(4) we get,48y=192 ⟹y=4Now let us eliminate y.Multiplying eqn(1) with 13 then we get,169x+143y=91Multiplying eqn(2) with 11, we get121x+143y=814Subtracting eqn(6) from eqn(5),we get x=2So x=2 and y=4 is our solution |
