Question

x-y=a+b,ax+by=a2-b2 by cross multiplication method​

Answer 1

Answer:

x = a and y = -b

Step-by-step explanation:

Given Equations are,

x - y = a+b

x - y - (a+b) = 0 ....................(1)

ax + by = a²-b²

ax + by - (a²-b²) = 0 .......................(2)

here,

since, 

There exist unique solution,

By cross multiplication method we get,

First Consider,

Secondly consider,

Therefore, x = a and y = -b
