C. 155
Explain:
40 + 35 + 25 + 20 + 35 = 155
x < -9 or x > 7
x + 1 < -8
x < -9
x + 1 > 8
x > 7
... when the inequality sign is facing the x, x is GREATER and it resembles an OR statement. I personally like to think of it as: greater than (greatOR than) = or statement; less than (less thAND) = and statement.
Divide both sides
3x+y-6=0
move variable
6x=12-2y
divide
x=2-1/3y
solve
Final answer:
x=2
