To start off your going to plug in 4x into the equation. Which will turn into 5x + 4x = 36. You will add 5 and 4 since they both have an x in it. Which would leave you to 9x = 36. Only thing left to do is divide 36 by 9. Which would equal to 4 and that will be your answer. X=4

-4x-2(8x+1)=-(-2x-10)
Andrew [12]
Answer: -6/11

-4x - 2(8x + 1) = -(-2x - 10)               Distributive Property
-4x - 16x - 2 = 2x + 10                     Combine like terms
-20x - 2 = 2x + 10                           Subtract 2x from both sides
-22x - 2 = 10                                   Add 2 to both sides
-22x = 12                                         Divide by -22 for both sides
x = -6/11                                           Answer!
