Answer:
A. When both sides of the equation are simplified, the coefficients are the same.
Explanation:
An equation has infinite solutions when both sides of the equation are simplified, the coefficients are the same.
For example, given the following equation:
3x + 8 = x + 2x + 8
Simplifying:
3x + 8 = 3x + 8
In this case, ALL values of 'x' satisfies the equation.
