Question

The pair of equations y = 0 and y = -7 has
(a) one solution
(b) two solutions
(c) infinitely many solutions
(d) no solution​

Answer 1

Answer:

(a) one solution.....

Step-by-step explanation:

Here,

y=0.........given

y= -7............ given

Now,

In both cases variable y is same.

And y=0 is of no value

Seconldy,

LHS=RHS

THEREFORE, y=y

Hence both have same variable y and therefore has only one solution-

y= -7
