| Answer» 2x-5y=3-1st equation3x-y=11-2nd equationFrom 1st equation,2x-5y=32x=3-5yX=(3+5y)/2Put value of x in 2nd equation3{(3+5y)/2}-y=11(9+15y)/2-y=119+15y-2y/2=11(here I take the LCM)9+13y=22(2 multiply with 11 and becomes 22)13y=22-913y=13Y=13/13Y=1Put value of y in 1st equation2x-5(1)=32x-5=32x=3+52x=8X=8/2X=4 | |
