Given 3x+y=11 call as eq 1 -2x+y=1 call as eq 2 Subtract 1&2 and consider simaltaneously We get "y" will be cancelled So, 5x=10 x=10/5 X=2 Substitute x=2 in eq 1 3x+y=11 3(2)+y=11 6+y=11 Y=11-6 Y=5 Therefore x=2 and y=5
S6=72 6a+15d=72 call as eq 1 T2=7(a+4d) a+d=7a+28d 6a+27d=0 call as eq 2 Consider the eq 1&2 simultaneously 6a+15d=72 eq 1 6a+27d=0 eq 2 Subtract 1&2 We get -12d=72 d=-6 evaluate d=-6 in eq 2 We get a=27 To find s10 =10/2(2*27+(10-1)-4) =5(54-36) =5(18)
