ok, so if you start with
2x - 3 = 0

Add 3 to both sides:
2x - 3 + 3 = 0 + 3, and reduce to:
2x = 3 ( +3-3 = 0, 0+3 = 3)
now divide both sides by 2
2x / 2 = 3 / 2
since 2 X's divided by 2 is 1 x, reducing gives you:
x = 3/2 = 1.5

That's solving an algebraic equation.
Basically, you're trying to isolate the variable (x) on one side of the equation by itself, which gives you the value for it (x). To isolate it, you use different methods like adding, subtracting, multiplying and dividing numbers from BOTH SIDES, thus keeping the equation valid, and eventually leading to the form:
x = ???, which is the solution.

The Zero Product Property in this case tells you for what value of x makes the equation equal to zero. This is used commonly for finding roots or solutions to various polynomial equations.

This particular equation, set 2x -3 = 0...then add three to both sides, then divide by two. That gives the result of 3/2 or 1.5.

Perhaps, if you rewrite the equation:
2x - 3 = 0
Begin to isolate the 2x term on the left by adding 3 to both sides:
2x = 3
Finally, divide both sides by 2:
x = 3/2 = 1 1/2.
