Question

if (a,a/2) is a solutionof the equation x+4y+5=0 find a​

Answer 1

Answer:

interchange the values of x and y with a and a/2 then we get a= -5/4

Answer 2

Answer:

a=-5/3

Step-by-step explanation:

Given. eqn. x+4y+5=0

and (a, a/2) is solution

solution. putting x=a

and y=a/2

so,

a+4a/2+5=0

a+2a+5=0

3a+5=0

3a=-5

a=-5/3
