Step-by-step explanation:

Step 1: Define Systems

1/2y = 4

x - 1/2y = 2

Step 2: Solve for y

  1. Define equation:                    1/2y = 4
  2. Isolate y:                                 y = 8

Step 3: Solve for x

  1. Define equation:                    x - 1/2y = 2
  2. Substitute in y:                       x - 1/2(8) = 2
  3. Multiply:                                  x - 4 = 2
  4. Isolate x:                                 x = 6

Answer: (6,8)

Step-by-step explanation:

1/2y = 4          

x - 1/2y = 2    

First  solve for y in the first equation.

1/2y = 4      Divide both sides by 1/2

y  =  8  

NOw substitute the value of y into the second equation and solve for x.

x

x - 1/2(8) = 2

x - 4 = 2

  +4     +4

x = 6    

THis makes the solution  (6,8)
