Solve for x and yX/a +y/b = 2ax - by = a2- b2 |

Answer» x/a + y/b = 2ay + xb = 2ab----------( 1 )ax - by = a² - b²---------( 2 )from-----( 1 ) &-------( 2 )multiply ( 1 ) by "a" ( 2 ) by "b"abx + a²y = 2a²babx - b²y = ba² - b³-------------------------------------------------y(a² + b²) = 2a²b - ba² + b³y(a² + b²) = a²b + b³y(a² + b²) = b(a² + b²)y = b [ put in -----( 1 )]we get,ay + xb = 2aba(b) + xb = 2abxb = 2ab - abx =ab/bx=a is that a2 or a^2 |
