Answer:

k = 7

Step-by-step explanation:

Step 1: Write equation

-18 = 5 - (6k - 19)

Step 2: Solve for k

Distribute negative: -18 = 5 - 6k + 19

Combine like terms: -18 = -6k + 24

Subtract 24 on both sides: -42 = -6k

Divide both sides by -6: k = 7

Step 3: Check

Plug in k to verify it's a solution.

-18 = 5 - (6(7) - 19)

-18 = 5 - (42 - 19)

-18 = 5 - 23

-18 = -18
