Question

(a+c)x - (a-c)y =2ab - (1)
(a+b)x - (a-b)y =2ab -(2)​

Answer 1

Answer:

x = (-y) & b = c

Step-by-step explanation:

(a+c)x - (a-c)y - (a+b)x + (a-b)y = 2ab - 2ab = 0

or, ax+cx-ay+cy-ax-bx+ay-by = 0

or, cx + cy - bx - by = 0

or,   c(x+y) - b(x+y)   = 0

or,    (x+y) (c-b)   = 0

∴ (c-b) = 0                           ;     (x+y) = 0

or,  c   =  b                           ;        x   = (-y)
