Step-by-step explanation:

Step 1: Define Systems

y = x + 5

2x + y = 2

Step 2: Solve for x

Substitution

  1. Substitute in x:                     2x + x + 5 = 2
  2. Combine like terms:            3x + 5 = 2
  3. Isolate x term:                      3x = -3
  4. Isolate x:                               x = -1

Step 3: Solve for y

  1. Define equation:                    y = x + 5
  2. Substitute in x:                       y = -1 + 5
  3. Add:                                        y = 4

Answer:

y = x + 5

2x + y = 2

2x + x + 5 = 2

3x + 5 = 2

3x = -3

x = -1

y = -1 + 5

y = 4

so x = -1 and y = 4
