Answer 2

It seems like you've provided a system of linear equations. We can solve this system of equations using different methods, such as substitution or elimination. Let's solve it using the elimination method.

Given equations:

1. $2x + 4y = 26$
2. $x - 5y = -1$

To eliminate one of the variables, we can multiply the second equation by 2 and then subtract the first equation from the modified second equation. This will eliminate the variable $x$:

Multiplying equation 2 by 2: $2(x - 5y) = 2(-1)$ $2x - 10y = -2$

Now subtract the first equation from the modified second equation: $(2x - 10y) - (2x + 4y) = -2 - 26$ $2x - 10y - 2x - 4y = -28$ $-14y = -28$

Solve for $y$: $y = -28/-14 = 2$

Now substitute the value of $y$ into one of the original equations, let's use equation 2:

$x - 5(2) = -1$ $x - 10 = -1$ $x = -1 + 10$ $x = 9$

So the solution to the system is $x = 9$ and $y = 2$.
