(2) Mr. Kork sold his car for $8,400. This was $200 more than two fifths of what he had paid for the car originally. How much had Mr. Kork paid for the car?
Answers:(2) Mr. Kork sold his car for $8,400. This was $200 more than two fifths of what he had paid for the car originally. How much had Mr. Kork paid for the car? Let x = the amount he paid for his car then, (2/5)x + 200 = 8400 solve for x multiply through by 5 2x + 1000 = 42000 2x = 41000 x = 20500 He paid $20,500 for the car Check One problem at a time QED

Question:Please give me the answers to these problems and explain to me how you found the answers. Show your work.
Simplify the espression: 2(5  3)
Solve for x:
1. x=(4)*(6  7) * = multiply sign
2. 6= 9 + 8x
3. x/7  5 =16
4. 24= 6  3x
5.6/x = 42
Answers:2(5  3)> multiply the 2 with 5 and 3 = (2*(5))  (2*(2)) = (10  4) = 6 1. x=(4)*(6  7) first do 6  7 x = (4)*(13) now multiply 4 with 13 x = 52, since both 4 and 13 are negative, the answer is positive 2. 6= 9 + 8x, first isolate the 8x by adding 9 on both side of the equation 6 + 9 =  9 + 8x 15 = 8x, now isolate the x by dividing 8 by both side of the equation 15/8 = 8x/8 15/8 = x 3. x/7  5 =16, isolate the x/7 by adding both sides by 5 x/7 5 +5 = 16 + 5 x/7 = 21, isolate the x by multiplying both side of the equation by 7 x/7 x 7 = 21 x 7 x = 21 x 7 x =147 4. 24= 6  3x, isolate the 3x by subtracting both side by 6 24  6 = 6  6  3x 30 = 3x, isolate the x by dividing both sides by 3 30/3 = 3x/3 10 = x 5.6/x = 42, isolate the x by multiplying both side by 1/6 6/x*1/6 = 42* 1/6, now the 6 in the 6/x can cancel out with 1/6 x = 42*1/6 x = 42/6 = 7

Question:How do I solve:
n+5
____ =1
16
Solve for n and how?
Answers:multiply both sides by 16 to get rid of the 16 on the left then 5. So its n+5 (16) = 1 (16) 16 N+5=16 5 5 n=11

Question:I need an algebra calculator that is free and shows you steps. I am looking at the answer key to this portion of questions I am doing and it doesn't show how they got the answer. Please? No pay sites please. I want to learn how to do the steps, that is why I am asking for them to be shown. I know myalgebra.com has a calculator but to show steps it takes a payment. Please don't tell me that I shouldn't use a calculator, I just want to use it on a couple equations so that I know that I am doing the steps correctly. Because as of right now, I have no idea what I am doing.
