More Math. Please help. *10 points* =)?

Solving Equations in General:

1: 6x - 4x + 2 = 10

2: 4 + 10x = 18 + 17x

3: 6x + 3 = 8x - 17 - 4

4: 40 + 1.5h = 3.5h

5: 6x - 2 = x + 13

6: 5y - 3 = 2y + 12

7: 4k - 3 = 3k + 6 - 2

8: 5m + 3 = 3m + 9

9: 8 - x = 2x - 1

10: 2n - 5 = 8n + 10 - 3

11: 3a + 4 = a + 18

12: 6b + 14 = -7 - 5b + 4b

13: 5a - 14 = -5 + 8a

14: 3 + 4x = 3x + 6

15: 30 - 7z = 10z - 10 + 6

16: 8x - 3 = 7x + 2

17: -36 + 2w = -8w + w

18: 4p - 10 = p + 3p - 2p

19: 12x + 4 = 13x - 5

20: 11x + 33 = 15x + 5

    You just need to combine like terms (x's with x's and lone numbers with lone numbers) and solve for x. I'll show you a couple...20 though!?! :-D This stuff is easy...is your teacher any good?

    1.) 6x - 4x + 2 = 10...subtract 4x from 6x and then subtract 2 from both sides

    6x - 4x + 2 = 10

    2x + 2 - 2 = 10 - 2

    2x = 8...(divide by 2 on both sides)

    x = 4

    2.) 4 + 10x = 18 + 17x subtract 10x from both sides and 18 from both sides (you could also subtract 17 and 4, your choice, same answer).

    4 + 10x - 10x - 18 = 18 - 18 + 17x - 10x

    -14 = 7x...divide both sides by 7

    -2 = x

    That should give you a gist for it. Good luck, hope this helped

    1: 6x - 4x + 2 = 10

    2x + 2 = 10

    2x = 8

    x = 4

    2: 4 + 10x = 18 + 17x

    4 = 18 + 7x

    -14 = 7x

    -2 = x

    3: 6x + 3 = 8x - 17 - 4

    4: 40 + 1.5h = 3.5h

    40 = 3.5h - 1.5h

    40 = 2h

    20 = h

    5: 6x - 2 = x + 13

    6x = x + 15

    5x = 15

    x = 3

    6: 5y - 3 = 2y + 12

    5y = 2y + 15

    3y = 15

    y = 5

    7: 4k - 3 = 3k + 6 - 2

    4k = 3k + 7

    1k = 7

    k = 7

    8: 5m + 3 = 3m + 9

    5m = 3m + 6

    2m = 6

    m = 3

    9: 8 - x = 2x - 1

    8 = 3x - 1

    9 = 3x

    3 = x

    10: 2n - 5 = 8n + 10 - 3

    2n = 8n + 12

    -6n = 12

    n = -2

    11: 3a + 4 = a + 18

    3a = a + 14

    2a = 14

    a = 7

    12: 6b + 14 = -7 - 5b + 4b

    13: 5a - 14 = -5 + 8a

    14: 3 + 4x = 3x + 6

    15: 30 - 7z = 10z - 10 + 6

    16: 8x - 3 = 7x + 2

    17: -36 + 2w = -8w + w

    18: 4p - 10 = p + 3p - 2p

    19: 12x + 4 = 13x - 5

    20: 11x + 33 = 15x + 5

    Yeah, you get the gist of it.

    This is like 6th grade math.

    You're ridiculous.

    While I can't solve your homework for you, I can show you an example.

    6x - 4x + 2 = 10

    Now, you want to get all the x's on one side and the non-x's on the other side. So what do you do?

    6x-4x+2=10

    -2 -2

    6x-4x=8

    What values do you see in common?

    6x and 4x are the same. So, 6x-4x=8

    2x=8

    Divide 8 by 2

    x=4!

    ok, you won't be in a position to be severe, it extremely is easy! ok, unique $30. finished of scholars: 3; each and every make contributions with 10 funds. cost of the watch: $25.00 Paid to the shopkeeper: $25 Trainee's income: $2 ok, 25+2= 27 Plus, 3 (each and every student won a million greenback returned) answer 27+3=30 Do the concern backwards, it promises the respond. Hesabi replaced right into a rather clever guy huh?

    20 problems and you will give only 10 points. So, I can't waste time in only one question. I will show you one and I will try to answer rest.

    1.6x -4x+2=10 ==> 2x+2=10 ==> 2x=8 ==> x = 4

    2.x = -2

    3. 12

    4. 20

    5. 3

    6. 5

    7. 7

    8. 3

    9. 3

    10. -2 .............. 20. x = 7
