4) Solve the equation below. You can type out your steps, record your steps or upload a picture of your steps. Make sure to show/explain every step as well as your final answer.

4(x - 5) - 2 = 56

4x-20=58

                   +20 +20

               4x=78

                /4  /4

                 x=19.5

Step-by-step explanation: Parenthesis first. Multiply 4 times x (which is 4x) and 5 times 4 (which is 20). So you get 4x-20-2=56. Move the (-2) over to the other side using inverse operations, making it 4x-20=58. Then move over the 20, again using inverse operations, making it 4x=78. Then isolate the variable by dividing both sides by 4 leaving you with x=19.5. You can check the work by plugging it in:

4(19.5-20)-2=56

78 - 20 = 58  (moved the -2 over to the other side)

58 = 58. That is true so the answer is correct.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

2x^2+5x+17
