Question

How many solutions does this equation have?-4k + 4k = 0

Answer 1

Let's try so solve this equation:

`\begin{gathered} -4k+4k=0 \\ 0=0 \end{gathered}`

When you have a result of 0 = 0, that means the equation has infinite solutions, that is, any value of k we use would satisfy the equation.

So the equation has infinitely many solutions.
