Step-by-step explanation:

Step 1: Define Systems

y = -3x + 10

y = -2x + 6

Step 2: Solve for x

Substitution

1. Substitute in y:                         -3x + 10 = -2x + 6
2. Add 3x on both sides:             10 = x + 6
3. Isolate x:                                   4 = x
4. Rewrite:                                    x = 4

Step 3: Solve for y

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