Find the value a at which the solution to the equation (a -1.5) (3x – 5) = 0 is any number.

As you know, when multiplying any number by 0, we end up with 0. In the expression (a -1.5) (3x – 5) = 0, we need to find the value of a, and x is the root of the equation. The root of the equation must be any number and we do not touch that part of the equation. We are left with a part of the equation (a -1.5), which should be equal to 0. a – 1.5 = 0; a = 1.5.
Answer: a = 1.5
