Answer 2

You have a system of two equations with two variables:

1. $x + 5y = 27$
2. $2x - y = -1$

There are several methods to solve this system, and one common approach is to use the method of substitution or elimination. In this case, I'll demonstrate the elimination method.

First, you can multiply the second equation by 5 to make the coefficients of $y$ in both equations equal:

1. $x + 5y = 27$
2. $10x - 5y = -5$

Now, you can add the two equations together to eliminate the $y$ variable:

$(x + 5y) + (10x - 5y) = 27 - 5$

This simplifies to:

$11x = 22$

Now, divide both sides by 11 to isolate (x:

$x = 22 / 11$

$x = 2$

Now that you have found $x$, you can substitute this value into one of the original equations to find $y$. Using the first equation:

$x + 5y = 27$

$2 + 5y = 27$

Subtract 2 from both sides:

$5y = 25$

Now, divide both sides by 5 to solve for (y:

$y = 25 / 5$

$y = 5$

So, the solution to the system of equations is $x = 2$ and $y = 5$.
