Answer 2

It looks like you've provided a system of two linear equations with two variables, $x$ and $y$:

Equation 1: $5x - 4y - 6 = 0$ Equation 2: $7x + 4y - 30 = 0$

To solve this system of equations, we can use either the substitution method or the elimination method. Let's use the elimination method:

Adding the two equations together will eliminate the $y$ term, allowing us to solve for $x$:

Adding the equations: $(5x - 4y - 6) + (7x + 4y - 30) = 0 + 0$ Simplifying: $12x - 36 = 0$ Solving for $x$: $12x = 36$ $x = 3$

Now that we have $x = 3$, we can substitute this value into either of the original equations to solve for $y$. Let's use Equation 1:

$5x - 4y - 6 = 0$ $5(3) - 4y - 6 = 0$ $15 - 4y - 6 = 0$ $-4y + 9 = 0$ $-4y = -9$ $y = \frac{9}{4}$

So, the solution to the system of equations is $x = 3$ and $y = \frac{9}{4}$.
