Answer: (1,-1)Step-by-step explanation: - You can multiply the first equation by -1 - Add the equations. - Solve for x, as following: [tex]\left \{ {{-5x - 4y = -1} \atop {-3x + 4y = -7}} \right.\\------\\-8x=-8\\x=1[/tex] - Substitute the value of x into any of the original equations and then you must solve for y: [tex]5(1)+4(y)=1\\4y=-4\\y=-1[/tex] Therefore, the solution is: (1,-1)
