297(x - 2y = 3(3x-y=4


Ответы на вопрос

Ответ: (x=3+2y
(9+6y-y=4
(x=3+2y
(5y=-5>>>y=-1 тогда x=3+2*(-1)
X=1
Ответ x=1,y=-1
Пошаговое объяснение:



It looks like you have two equations that seem to be missing closing parentheses. I'll assume you meant to write:
- 297(x - 2y) = 3
- 3(3x - y) = 4
If that's the case, we can solve this system of equations to find the values of x and y.
Let's start with the first equation:
297(x - 2y) = 3
Expand the equation:
297x - 594y = 3
Now, let's move on to the second equation:
3(3x - y) = 4
Expand the equation:
9x - 3y = 4
Now, we have a system of two equations:
- 297x - 594y = 3
- 9x - 3y = 4
To solve this system of equations, we can use the method of substitution or elimination. Let's use the substitution method:
From equation 2, we can express y in terms of x:
9x - 3y = 4 => -3y = 4 - 9x => y = (9x - 4)/3
Now, substitute this value of y into equation 1:
297x - 594y = 3 => 297x - 594((9x - 4)/3) = 3 => 297x - 198x + 264 = 3 => 99x = -261 => x = -261/99 => x = -3
Now that we have the value of x, let's find y by substituting x back into either equation 1 or 2. Let's use equation 2:
9x - 3y = 4 => 9(-3) - 3y = 4 => -27 - 3y = 4 => -3y = 4 + 27 => -3y = 31 => y = -31/3
So the solution to the system of equations is x = -3 and y = -31/3.
