Answer:
The answer to your question is x = 2, y = -3
Explanation:
Data
 5x + 4y = -2 Equation l
 x - 4y = 14 Equation ll
Process
-Sum up the equation
Result
 6x = 12
Solve for x  x = 12/6
 x = 2
-Substitute x in equation ll
 2 - 4y = 14
-Solve for y
 -4y = 14 - 2
 -4y = 12
 y = 12/-4
-Result
 y = -3
