Pls answer only if you know........​

Answer 1

Answer:

$x/a-y/b= a - b \\ </p><p>x/a \times ab=y/b \times ab \\ \frac{bx}{a} = \frac{ay}{b} \\ {b}^{2}x = {a}^{2}y \\ x = \frac{{a}^{2}y}{ {b}^{2} }$

$ax + by = {a}^{3} + {b}^{3} \\a \times \frac{ {a}^{2}y }{ {b}^{2}} + by = {a}^{3} + {b}^{3} \\ \frac{y}{ {b}^{2} } ( { a}^{3} + {b}^{3}) = {a}^{3} + {b}^{3} \\ y = {b}^{2} \\ therefore\\ x = {a}^{2}y \div {b}^{2} \\ x = {a}^{2}$
