Explain how you know that the equations 1/4 equals 2x and 1/4 divided by x equals 2 have the same solution. then, find the solution.

1/4 = 2x
To solve this equation you have to move the X. To move the X you need to divide it.
So it's now 1/4 ÷ X = 2.

1/4 = 2x is equivalent to 1/4 ÷ X = 2 because when it's simplified it equals 1/4 ÷ X = 2.
