Question

Solve the following system of linear equation by any method: A. (a-b)x + (a+b)y = a²-2ab-b² (a+b)x + (a+b)y = a²+b² (using only cross-multiplication method) B. ax - by = a²+b² x - y = 2b C. x/a + y/b = a+b x/a² + y/b² = 2 D. x + y = a+b ax - by = a²-b² E. x/a + y/b = 2 ax - by = a² - b²

x + y = a + b, a x - b y = a^{2} - b^{2}

x

y

a x + b y = a - b

b x - a y = a + b

\frac{a x}{b} - \frac{b y}{a} = a + b

a x - b y = 2 a b

Factorise: $2 a x + 2 b x - a y - b y$

(a - b) x + (a + b) y = 2 a^{2} - 2 a b^{2}, (a + b) (x + y) = 4 a b
