Jillana begins to solve a linear equation that results in a variable expression set equal to the same variable expression. which is the best interpretation of this solution?
a. the equation has one solution: x = 0.
b. the equation has one solution: x = 1.
c. the equation has no solution.
d. the equation has infinite solutions.

While solving a linear equation if we find the variable expression at one side is equal to the variable expression on the other side then we can say that this condition is always true.

And we can take any value for the variable for which the result holds true.

For example, if we get

Hence, in such case the equation has infinitely many solutions.

Therefore, d is the correct option.
