Question

X= 4 and y = - 2 is the solution of the linear equation
a) x + y = 0
(.b)x+2y=0
c) x + y = 6
d)x-y=2​

Answer 1

Answer:

b) x + 2y = 0

Step-by-step explanation:

x = 4 , y = -2

Now,

4 + (2 ×-2) = 0

=) 4 -4 = 0

=) 0 = 0

Hence, proved.

Answer 2

(b).x+2y=0

solution:

L.H.S

=x+2y

=substitung the given valued of x and y

=4+2(-2)

=4+(-4)

=4-4

=0

hence L.H.S=R.H.S
