Question

(12у-18)*(1,6+0,4у)=0

Answer 1

Ответ:

y = 3/2 / y = -4

Пошаговое объяснение:

Либо первая, либо вторая скобка = 0

12y-18 = 0 -> y = 3/2

1.6+0.4y = 0 -> y = -4

Answer 2

To solve the equation $(12у-18) \cdot (1,6+0,4у) = 0$, we can apply 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 equal to zero. In this case, we have a product of two expressions:

$(12у-18) \cdot (1,6+0,4у) = 0$

Now, we can set each factor equal to zero and solve for $y$:

1. $12у-18 = 0$ Add 18 to both sides: $12у = 18$ Divide both sides by 12: $у = \frac{18}{12}$ Simplify the fraction: $y = \frac{3}{2}$

2. $1,6+0,4у = 0$ Subtract 1.6 from both sides: $0,4у = -1,6$ Divide both sides by 0.4: $y = -4$

So, the solutions for the equation are $y = \frac{3}{2}$ and $y = -4$.
