Answer:

x = -2 ; y = -6

Step-by-step explanation:

Let y = 3x be eqn.1

So putting eqn.1 in 5x + 4y = -34 gives ,

[tex]5x + 4y = - 34[/tex]

[tex] = > 5x + 4(3x) = - 34[/tex]

[tex] = > 5x + 12x = - 34[/tex]

[tex] = > 17x = - 34[/tex]

[tex] = > x = \frac{ - 34}{17} = - 2[/tex]

Putting the value of x in eqn.1 gives :-

[tex]y = 3x = 3 \times ( - 2) = - 6[/tex]
