Question

Find the values of x and y in which
X+ay=b..... Eq 1
ax-by=c.... Eq 2

By elimination method

Answer 1

Ur solution dear............

Answer 2

x + ay=b ---Eq 1. ]×b

ax - by = c ---Eq 2. ]×a

bx +aby =b^2

a^2×x -aby =ac
+
x(a^2+b)=ac+b^2
after solving this
x=ac+b^2/a^2+b
put in eq--2
ac+b^2/a^2+b+ay=b
y=ab-c/a^2 + b
