Step-by-step explanation:

Step 1: Define Systems

y = -6x - 16

-2x + 4y = -2

Step 2: Solve for x

Substitution

Substitute in y:                                                                                                -2x + 4(-6x - 16) = -2Distribute 4:                                                                                                    -2x - 24x - 64 = -2Combine like terms:                                                                                       -26x - 64 = -2[Addition Property of Equality] Add 64 on both sides:                                -26x = 62[Division Property of Equality] Divide -26 on both sides:                            x = -31/13

Step 3: Solve for y

Define original equation:                                                                               y = -6x - 16Substitute in x:                                                                                                y = -6(-31/13) - 16Multiply:                                                                                                           y = 186/13 - 16Subtract:                                                                                                          y = -22/13

$22. if larry's profit were to minimize by one for every hour his store were to be closed, we would subtract 30 by 8.
