Answer: (1,-1)

Step-by-step explanation:

- You can multiply the first equation by -1

- Add the equations.

- Solve for x, as following:

$\left \{ {{-5x - 4y = -1} \atop {-3x + 4y = -7}} \right.\\------\\-8x=-8\\x=1$

- Substitute the value of x into any of the original equations and then you must solve for y:

$5(1)+4(y)=1\\4y=-4\\y=-1$

Therefore, the solution is: (1,-1)
