Question

For which value of c the pair of equations 2x+2y– and 4x+4y– chave a infinitely many solutions​

Answer 1

Answer:

since, the given equation has infinitely many solutions

therefore, a1\a2= b1/b2= c1/c2

Now a1/a2=2/41/2

b1/b2=2/4=1/2

so, c1/c2 must be 1/2, hence it can be any number e.g 3/6
