Question

how to create an equation with infinitely many solutions.

Answer 1

Answer:

See below.

Step-by-step explanation:

An equation with infinite solutions is, strictly, an identity.

An example is 2(x + 3) = 4x + 6

Simplifying  we get 4x + 6 = 4x + 6. We can replace by any value of x  and the equation will hold true.
