Final answer:
A linear equation in one variable can have any number of solutions, depending on the equation.
Step-by-step explanation:
A linear equation in one variable can have any number of solutions. The number of solutions depends on the relationship between the coefficients and constants in the equation.
For example, the equation y = 2x has infinitely many solutions because for any value of x, there is a corresponding value of y that satisfies the equation.
On the other hand, the equation 3x + 2 = 0 has only one solution because there is only one value of x that makes the equation true.
