1. 7x-1 = 2x+5

2. 3y+1 = 4y-6

3. 10-y = 2y+3

4. 6x+2 = 1-x

5. 3a-10 = 4+a

6. 5y+4 = 4y+5

7. b+3 = 2b-7

8. 2x-1 = x-3

9. 2w+3 = 4w-5

10. 6n+4 = n-11

please help in any way you can...thnx

**Ms. Sue**, Wednesday, August 27, 2008 at 6:17pm7x-1 = 2x+5

First get the unknowns on one side of the equation.

7x - 2x = 6

5x = 6

x = 1.2

You can check that by substituting.

7(1.2) - 1 = 2(1.2) + 5

8.4 - 1 = 2.4 + 5

7.4 = 7.4

Now -- please try a couple on your own. We'll be glad to check them for you.

3y+1=4y-6 is Y= 1

umm.... i think that i need more help with 10-y=2y+3.....

6x+2=1-x is X= 0.42

3a-10=4+a is A= 7

5y+4=4y+5 is Y= 1

b+3=2b-7 is B= 3.3

2x-1=x-3 is X= 2

2w+3=4w-5 is W= 1.3

6n+4=n-11 is N= 2.14

**Ms. Sue**, Wednesday, August 27, 2008 at 7:35pm3y+1=4y-6 is Y= 1

1 + 6 = y

7 = y

10-y=2y+3

10 - 3 = 3y

**Tiffany**, Wednesday, August 27, 2008 at 8:43pmI have this word problem that I can't figure out. The problem is:

A 15 lb weight is positioned 10 in. form a fulcrum. At what distance from the fulcrum must a 12 lb weigt be positioned to keep the scale balanced?

The substitute that I had today said that the 12 lb. weight would have to be further away from the fulcrum than the 15 lb., but my mom says the opposite.

**Harsh**, Saturday, October 20, 2012 at 12:52amI have a trapezoid, and the bases are lengths 18 inches and 12 inches. Dividing the trapezoid into unequal parts are triangles. In other words, the trapezoid is divided into 7 unequal triangles. 4 triangles are shaded. How do I find the area of the shaded region of the trapezoid?
