Question 258157
The given equations are,
          8x = 2y + 5   ...(1)
          3x = y + 7 
          3x-7 = y
          y = 3x-7
Substituting in (1), we get
          3x = 2(3x-7)+5
          3x = 6x-14+5
          3x-6x = -9
          -3x = -9
          x = (-9)/(-3)
          x = 3
Substituting in (1), we get
          3*(3) = 2y+5
          9-5 = 2y
          2y = 4
          y = 4/2
          y = 2
So the solution is x = 3, y = 2
