Question

Решите систему X:2=у:3 х+у=4

Answer 1

Вырази из второго x=4-y
потом подставьв первое (4-y)2=y\3
теперь умножи все на 6
получается 12-3y=2y
5y=12
y=2.4
теперь подставляем во второе уравнение
х+2.4=4
х=1.6

Answer 2

I can help you solve the system of equations. The system is equivalent to:

$$\begin{cases} x = \frac{2}{3}y \\ x + y = 4 \end{cases}$$

To solve it, we can substitute the first equation into the second one and get:

$$\frac{2}{3}y + y = 4$$

Simplifying and solving for y, we get:

$$\frac{5}{3}y = 4$$ $$y = \frac{12}{5}$$

Then, we can plug this value of y into the first equation and solve for x:

$$x = \frac{2}{3} \cdot \frac{12}{5}$$ $$x = \frac{8}{5}$$

Therefore, the solution of the system is:

$$(x, y) = \left(\frac{8}{5}, \frac{12}{5}\right)$$
