 Hi and welcome to the session. Let's work out the following question. The question says solve for x and y x upon a plus y upon b is equal to 2 and a x minus b y is equal to a square minus b square Let us start with the solution to this question We have x upon a plus y upon b is equal to 2 this implies b x plus a y is equal to 2 a b this implies b x plus a y minus 2 a b is equal to 0 this we call 1 and a x minus b y minus a square minus b square is equal to 0 and this we call 2 now by cross multiplication We get x upon minus a into a square minus b square minus Minus b into minus 2 a b is equal to y or minus y divided by Minus b into a square minus b square minus a into minus 2 a b is This is This is equal to 1 upon b into minus b Minus a into a this implies x upon Minus a into a square minus b square minus 2 a b square is Equal to minus y divided by minus b into a square minus b square Plus 2 a square b is equal to 1 upon minus b square minus a square this implies x divided by Minus a into a square minus b square plus 2 a Sorry, this is 2 b square is Equal to minus y divided by Minus b into a square minus b square Minus 2 a square is equal to 1 upon minus a square plus b square This implies x divided by minus a into a square plus b square is Equal to minus y divided by minus b into minus a square minus b square is Equal to minus Sorry, this is 1 divided by minus a square plus b square This implies x upon minus a into a square plus b square is equal to y upon now this is Equal to this that is 1 upon minus a square plus b square This implies that x is equal to Minus a into a square plus b square divided by minus a square plus b square This is equal to a so x is equal to a and Minus y is equal to minus b into minus a square minus b square divided by minus a square plus b square This implies that y is equal to minus b into a square plus b square divided by, divided by minus a square plus b square, this gets cancelled from numerator denominator we are left with b. Or we could here also write b into minus 1 in the denominator also. So minus 1 gets cancelled with minus 1, we are left with b. So our answer to this question is that x is equal to it and y is equal to b. So I hope that you understood the solution and enjoyed the session. Have a good day.
