Solve ax/b -by/a= a+b,ax-by=2ab |
|
Answer» {tex}\\frac { a x } { b } - \\frac { b y } { a } = a + b{/tex}{tex}\\Rightarrow{/tex}\xa0{tex}a^2x - b^2y = a^2b + ab^2{/tex}............(i){tex}ax - by = 2ab{/tex}..............................(ii)Multiply (ii) by -b, we get{tex}-abx + b^2y = -2ab^2{/tex}.......................(iii)Adding (i) and (iii), we get{tex}a^2x - abx = a^2b + ab^2\xa0- 2ab^2{/tex}{tex}\\Rightarrow{/tex}\xa0{tex}x(a^2\xa0- ab) = a^2b - ab^2{/tex}{tex}\\Rightarrow x = \\frac { a b ( a - b ) } { a ( a - b ) }{/tex}{tex}\\Rightarrow x = b{/tex}Substituting x = b in (ii), we geta(b) - by = 2ab{tex}\\Rightarrow{/tex}\xa0-by = ab{tex}\\Rightarrow{/tex}\xa0y = -aSo, x = b and y = -a axb−bya=a+b ⇒ a2x−b2y=a2b+ab2............(i)ax−by=2ab..............................(ii)Multiply (ii) by -b, we get−abx+b2y=−2ab2.......................(iii)Adding (i) and (iii), we geta2x−abx=a2b+ab2−2ab2⇒ x(a2−ab)=a2b−ab2⇒x=ab(a−b)a(a−b)⇒x=bSubstituting x = b in (ii), we geta(b) - by = 2ab⇒ -by = ab⇒ y = -aSo, x = b and y = -a |

Answer» U just gotta practice a bit more if ur still not confident enough and you\'ll do great! And ur ans is correct ? Yes Alpna I can 4/10x + 3/10y = 17/107/10x - 2/10y = 8/10 = 4x + 3y /10 = 17/10 4x + 3y = 17 -1st eqSimilarly 7x - 2y = 8 - 2nd eq x = 8+ 2y / 7 (from 2 )Putting value in eq 1 4 (8+2y /7 ) +3y =17 32+8y /7 +3y = 17 Solve and get the value of y Then put the value of y in equation no. 1 And get the value of x Easey peasy dude ? don\'t freak out because of the decimal and make it easy by dividing it by 10 or 100 or 1000 And then solve according to the question and you\'ll do fine .?? Are u able to understand it???? On taking LCM 4x+3y=17 7x-2y=8Now on multiplying 28x+21y=119 28x-8y. =32 y=3 and x=2 |
