Answer» X=1 and y=-1 Px+qy=p-q -(1)qx-py=p+q-(2)multiply(1) with p and eq2 with qPx2+pqy=p2-pq-(3)q2x-pqy=pq+q2-(4)add eq 3 and 4 Px2+qx2=p2+q2X(p2+q2)=p2+q2X=1Put this in eq 1P(1)+qy=p-qqy=p-q-pY=-q/qY=-1 Ye chap 3 ki optional ka q h. Multiply (i) by p and (ii) by q and add them and slove by elimination method ... Then answer is x=1 and y= -1 Ye konse chap ka h ?? |
