Answer:  ( 6, -4)

Step-by-step explanation:

Substitute the value of y in the second equation  into the first equation and solve for x.

5x - 7(-x + 2) = 58       Distribute

5x + 7x - 14 =58      Combine like terms

12x - 14 = 58

      +14    +14

12x =    72

x  = 6  

Input  the value for x intro one of the equations to solve for y .

5(6) - 7y = 58

30 -7y = 58

-30          -30

    -7y = 28

   y = -4
