Question

3-(x-2y) -4y = 182x-3y+3 = 2(3x-y)​

Answer 1

Ответ:

(x,у)=(3, -9)

Пошаговое объяснение:

3-(x-2y) -4y = 18

2x-3y+3 = 2(3x-y);

х= -15-2у

2х-3у=3=2(3х-у);

2(-15-2у)-3у+3=2(3(-15-2у)-у);

у= -9;

х= -15-2*(-9)

х=3

Проверка равенства:

3-(3-2*(-9))-4*(-9)=18

2*3-3*(-9)+3=2(3*3-(-9));

18=18

36=36

Answer 2

It looks like you have a system of three equations with two variables. Let's solve it step by step.

1. Equation 1: $3 - (x - 2y) - 4y = 0$

Simplifying Equation 1, we get: $3 - x + 2y - 4y = 0$ $3 - x - 2y = 0$ $x + 2y = 3$

2. Equation 2: $182x - 3y + 3 = 0$

3. Equation 3: $2(3x - y) = 0$

Let's work on simplifying Equation 2:

$182x - 3y + 3 = 0$

Rearrange it to get y in terms of x:

$3y = 182x + 3$ $y = \frac{182x + 3}{3}$ $y = 60.67x + 1$

Now, we can substitute this expression for $y$ into Equation 1 ($x + 2y = 3$):

$x + 2(60.67x + 1) = 3$ $x + 121.34x + 2 = 3$ $122.34x = 1$ $x \approx 0.0082$

Now that we have the value for $x$, we can find the corresponding value for $y$ using the expression we found for $y$:

$y = 60.67(0.0082) + 1$ $y \approx 1.5$

So, the solution to the system of equations is approximately $x \approx 0.0082$ and $y \approx 1.5$.
