-3x - 5 = 16 x=???

[need to right more because my question is too short stuff in brackets is irrelevant]

Given: lines a and b are parallel and line c is a transversal. prove: 2 is supplementary to 8 what is the missing reason in the proof? statement reason 1. a || b, is a transv 1. given 2. ∠6 ≅ ∠2 2. ? 3. m∠6 = m∠2 3. def. of congruent 4. ∠6 is supp. to ∠8 4. def. of linear pair 5. ∠2 is supp. to ∠8 5. congruent supplements theorem corresponding angles theorem alternate interior angles theorem vertical angles theorem alternate exterior angles theorem

Find the value of x in each case. give reasons to justify your solutions! d q ∈ pr

Which linear function represents the line given by the point-slope equation y + 1 = –3(x – 5)?
