Answer 1

Решение на фото. Умножаем вторую строчки на 0.2 и складываем. Получается 0х + 0у = 0, система уравнений имеет бесконечно много решений (какой бы икс или игрек мы бы не подставили будет 0)

Answer 2

It looks like you have a system of linear equations with two equations and two variables:

Equation 1: 1.2x - 1.7y = -4.4 Equation 2: -6x + 8.5y = 22

To solve for the variables x and y, we can use various methods, such as substitution or elimination. Here, I'll use the elimination method.

First, let's make the coefficients of one of the variables the same in both equations so that we can eliminate that variable. Let's work with the y term. The coefficients of y in the equations are -1.7 and 8.5. To eliminate the y term, we need to make these coefficients the same (but with opposite signs). We can achieve this by multiplying both sides of Equation 1 by 5:

Equation 1 (multiplied by 5): 6x - 8.5y = -22

Now, we can add Equation 2 to the modified Equation 1 to eliminate the y term:

(6x - 8.5y) + (-6x + 8.5y) = -22 + 22 0 = 0

This means that the two equations are dependent, and they represent the same line. In other words, there are infinitely many solutions that satisfy both equations. The solution set is the entire line described by the equations.

If you need a specific numerical solution, you'll need additional information or constraints to narrow down the solution to a unique point.
