Answer 2

Answer:

ax+by=a-b. →(1) and. bx-ay=a+b. →(2)

by elimination method,

eqn(1)+(2),

a-b=ax+by

+a+b=bx-ay

2a=x(a+b)-y(a-b)

a={x(a+b)-y(a-b)}/2. →(3)

put (a) value in eqn (1),

ax+by=a-b

ax+by={x(a+b)-y(a-b)}/2-b

ax+by=[{x(a+b)-y(a-b)}-2b]/2

2ax+2by=ax+xb-ay+by

ax+by=xb-ay. [ from(2)]

ax+by=a+b

b=ax+by-a(answer)
