give an example of an open equation?

An example of an open equation is: 3x + 5 = y.

give another one?

Another example of an open equation is: 2a - b + 7c = 3d.

An example of an open equation is:

2x + 5 = y

In this equation, the value of y depends on the value of x. The equation is open because it can have multiple solutions depending on the value assigned to x.

Sure! An example of an open equation is:

3x + 7 = y

In this equation, both the variable "x" and the variable "y" are unknown and can take on any value. The equation is considered open because it is not possible to solve it for a specific value of x and y without additional information or constraints.
