Step-by-step explanation:

Step 1: Define Systems

y = -x + 1

2x + 3y = 6

Step 2: Solve for x

Substitution

1. Substitute in y:                    2x + 3(-x + 1) = 6
2. Distribute 3:                         2x - 3x + 3 = 6
3. Combine like terms:           -x + 3 = 6
4. Isolate x terms:                   -x = 3
5. Isolate x:                              x = -3

Step 3: Solve for y

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