Step-by-step explanation:

Step 1: Define Systems

y = x + 8

x + y = 2

Step 2: Solve for x

Substitution

Substitute in y [2nd Equation]:                                                                         x + x + 8 = 2Combine like terms:                                                                                         2x + 8 = 2[Subtraction Property of Equality] Subtract 8 on both sides:                        2x = -6[Division Property of Equality] Divide 2 on both sides:                                  x = -3

Step 3: Solve for y

Substitute in x [1st Equation]:                                                                           y = -3 + 8Add:                                                                                                                   y = 5

21, i'm pretty sure it's right lol
