Question

X=1,y=2 is solution of the equation a2x+ay=3,then find the value of a

Answer 1

X=1
Y=2

2*1*a + a*2 = 3

2a + 2a = 3

4a = 3

a = 3/4

Answer 2

Answer:

x=1 & y=2

substituting these values in a2x+ay=3

a2(1)+a(2)=3

a2+2a-3=0

solving the above quadratic equation...

-b±√b$\sqrt{b^{2} -4ac}/2a$

we get 2 roots..

root 1:   2/3

root 2:  -2
