Answer 3

To solve the equation (2x - 18) * (4.2 + 0.7x) = 0, we can use the zero product property, which states that if the product of two factors is equal to zero, then at least one of the factors must be zero.

So, we have two factors: (2x - 18) and (4.2 + 0.7x). Setting each factor equal to zero, we can solve for x.

First factor: 2x - 18 = 0

Adding 18 to both sides: 2x = 18

Dividing both sides by 2: x = 9

Second factor: 4.2 + 0.7x = 0

Subtracting 4.2 from both sides: 0.7x = -4.2

Dividing both sides by 0.7: x = -6

Therefore, the solutions to the equation are x = 9 and x = -6.
