Step-by-step explanation:

Step 1: Define Systems

y = -4x + 1

11y = x + 146

Step 2: Solve for x

Substitution

  1. Substitute in y:                                                                                                   11(-4x + 1) = x + 146
  2. Distribute 11:                                                                                                     -44x + 11 = x + 146
  3. [Addition Property of Equality] Add 44x on both sides:                              11 = 45x + 146
  4. [Subtraction Property of Equality] Subtract 146 on both sides:                  -135 = 45x
  5. [Division Property of Equality] Divide 45 on both sides:                             -3 = x
  6. Rewrite/Rearrange:                                                                                             x = -3

Step 3: Solve for y

  1. Define original equation:                                                                                  y = -4x + 1
  2. Substitute in x:                                                                                                   y = -4(-3) + 1
  3. Multiply:                                                                                                           y = 12 + 1
  4. Add:                                                                                                                      y = 13
