Solve simultaneous equation for equation x and ym+(x+y)+ n(x-y)-(m²+mn+n²)=0n(x+y)+m(x-y)-(m²-mn+n²)=0 |

Answer» The simultaneous equations are m(x+y) +n(x-y)-(m²+MN+n²) =0 and n(x+y) +m(x-y)-(m²-mn+n²) =0. We have to solve those two equations for x and y. Now, m(x+y) +n(x-y)-(m²+mn+n²) =0 ⇒ x(m + n) + y(m - n) = m² + mn + n² ........... (1) And, n(x+y) +m(x-y)-(m²-mn+n²) =0 ⇒ x(m + n) - y(m - n) = m² - mn + n² ........... (2) Now, eliminating y from equations (1) and (2) we get, 2x(m + n) = 2(m² + n²) ⇒ (Answer) Similarly, eliminating x from equations (1) and (2) we get, 2y(m - n) = 2mn ⇒ (Answer) READ more on Brainly.in - brainly.in/question/14279180#readmore |
