Question

solve this?fast this is a equation. ​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

HEY MATE YOUR ANSWER IS HERE...

( a - b )x + ( a + b )y = a²- 2ab - b² -- eq1

( a + b ) ( x - y ) = a² + b²

→ ax - ay + bx - by = a² + b²

→ ( a + b )x - ( a + b )y = a² + b² ------ eq 2

★ NOW BY ELEMINATION ★

ADDING EQUATION

$( a - b)x + ( a + b)y \: = {a}^{2} - 2ab - {b}^{2} \\ \\ (a + b)x - (a + b)y \: = {a}^{2} + {b}^{2} \\ - - - - - - - - - - - - - - - - - - - \\ (a - b)x + (a + b)x \: = {a}^{2} - 2ab - {b}^{2} + {a}^{2} + {b}^{2}$

$(a - b + a + b)x = 2 {a}^{2} - 2ab \\ \\ (2a)x = 2a(a - b) \\ \\ x = (a - b)$

NOW PUT VALUE OF X IN Eq 2

$(a + b)(a - b) - (a + b)y = {a}^{2} + {b}^{2}$

${a}^{2} - {b}^{2} - (a - b)y = {a}^{2} + {b}^{2}$

$- (a - b)y = {a}^{2} + {b}^{2} - {a }^{2} + {b}^{2}$

$- (a - b)y = 2 {b}^{2}$

$y \: = - \frac{2 {b}^{2} }{ ( a - b \: \:) }$
