Question

Y = 1- 7х,4х - у = 32;​

Answer 1

Ответ:

у =1 - 7х 7х +у = 1

4х - у = 32, ⇒ 4х -у = 32 Теперь сложим почленно:

11х = 33,⇒ х = 3

у = 1 - 7х = 1 - 7*3 = 1 - 21 = -20

Ответ:(3; -20)

Answer 2

It seems like you're providing an equation system:

1. $Y = 1 - 7x$
2. $4x - y = 32$

You might want to solve this system of equations. To do that, we can substitute the expression for $Y$ from the first equation into the second equation:

$4x - (1 - 7x) = 32$

Now, let's solve for $x$:

$4x - 1 + 7x = 32$

Combine the $x$ terms:

$11x - 1 = 32$

Add 1 to both sides:

$11x = 33$

Divide both sides by 11:

$x = 3$

Now that we have the value of $x$, we can substitute it back into the first equation to find $Y$:

$Y = 1 - 7x$

$Y = 1 - 7(3)$

$Y = 1 - 21$

$Y = -20$

So, the solution to the system of equations is $x = 3$ and $y = -20$.
