Answer 2

To solve the equation (9y-2)(2.1-7) = 0, we can use the zero product property. According to this property, if the product of two factors is equal to zero, then at least one of the factors must be equal to zero.

Let's solve the equation step by step:

1. Expand the expression: (9y-2)(2.1-7) = 0 18.9y - 63y - 4.2 + 14 = 0 -44.1y - 4.2 + 14 = 0 -44.1y + 9.8 = 0

2. Move the constant term to the other side of the equation: -44.1y = -9.8

3. Solve for y by dividing both sides of the equation by -44.1: y = -9.8 / -44.1 y ≈ 0.222

Therefore, the solution to the equation (9y-2)(2.1-7) = 0 is y ≈ 0.222.
