4x + 2y = 56. 5x + y = 34. y = -5x + 34. 4x + 2(-5x + 34) =56. 4x -10x + 68 = 56. -6x = -12. x=2. 4(2) +2y = 56. 8+2y = 56. 2y = 48. y = 24.
x=2, y=24.

The value of k should equal to 4/3. You can multiply k on each side to get 4=3k and divide by 3 to get 4/3=k. Another approach is to reciprocate the RHS and LHS of the equation to get k/4=1/3, and then multiply by 4 on each side to get k=4/3.
