Step 1) Expand the terms in parenthesis:

(-6*3) + (-6*6x) - 6 = -258

-18 - 36x - 6 = - 258

Step 2) Combine like terms:

-24 - 36x = - 258

Step 3) Isolate the x term on one side of the equation while keeping the equation balanced:

-24 + 24 - 36x = -258 + 24

0 - 36x = -234

-36x = -234

Step 4) Solve for x while keeping the equation balanced:

(-36x)/-36 = (-234)/-36

(cancel(-36)x)/cancel(-36) = 6.5

x = 6.5
