Question

(х+ 5 = 73х + 2y = - 5​

Answer 1

Ответ:

х+ 5 = 7

3х + 2y = - 5​

х = 2

3х + 2y = - 5​

х = 2

3*2 + 2y = - 5​

х = 2

6 + 2y = - 5​

х = 2

2y = - 5 - 6

х = 2

2y = - 11

х = 2

y = - 5.5

Answer 2

It seems like you've provided a system of linear equations. Let's solve this system step by step.

The given system of equations is:

1. $x + 5 = 73x + 2y$
2. $73x + 2y = -5$

We'll start by solving the first equation for $y$ in terms of $x$: $x + 5 = 73x + 2y$ $2y = -72x + (x + 5)$ $2y = -71x + 5$ $y = -\frac{71x}{2} + \frac{5}{2}$

Now, let's substitute this expression for $y$ into the second equation: $73x + 2\left(-\frac{71x}{2} + \frac{5}{2}\right) = -5$

Now, we can solve for $x$: $73x - 71x + 5 = -5$ $2x + 5 = -5$ $2x = -10$ $x = -5$

Now that we have $x$, let's substitute it back into the first equation to find $y$: $y = -\frac{71x}{2} + \frac{5}{2}$ $y = -\frac{71(-5)}{2} + \frac{5}{2}$ $y = \frac{355}{2}$

So the solution to the system of equations is: $x = -5$ and $y = \frac{355}{2}$.
