\begin{aligned} & -5x+8y = 0 \\\\ & -7x-8y = -96 \end{aligned}
​

−5x+8y=0
−7x−8y=−96
​

x=x=x, equals
y=y=y, equals

Answer 1

Answer:

(x, y) = (8, 5)

Step-by-step explanation:

The equations are:

$-5x + 8y = 0 \hspace{20mm} \hdots (1)$

$- 7x - 8y = - 96 \hspace{20mm} \hdots (2)$

Adding (1) and (2), we get:

$- 5x - 7x + 8y - 8y = - 96$

$\implies - 12x = - 96$

⇒ x = 8

Substituting x = 8, in Equation (1), we get:

8y = 5x

$\implies 8y = 5(8) = 40$

⇒ y = 5

Therefore, the root of the equation: (x, y) = (8, 5).
