1. -4p - 3 = -2p + 7

2. -3(m+2) - 2(m-1) = -2

3. 1over3x + 1 = 2over3x - 4

4. 1-dover4 - dover2 = 7

5. 4a+5over3 - 3aover2 = -a
Can Anyone Help!
 
This thread wont last long and I wont give you the answers but I'll give you a few hints.

Get like variables and integers to the same sides. Example 2x+7 = x+9 could become x=2

An integer outside of () means you multiply each number or variable inside the ()s by that integer. Example 2(2x + 7) becomes 4x + 14.
 
^ Basically what he said. You can't add or subtract two "different" types of things, like you can't add something with a X or P variable to something with no variable or a different one. So you have to move them over to the other side.

Like this:

4p + 2 = 5p + 1
-4p = -4p
----------------
2 = p + 1
- 1 = - 1
----------------
1 = p

Sorry for all the crappy alignment, I was trying to do it the way I would write it on paper.
 
Other quick thing about Fractions: Multiply it by the LCM of the denominators. so if you have something like (3x/5)-(9x/4)=7x+3, multiply the whole thing by 20 to make things simpler.
 
Wow, I'm really having to think about this stuff haha ... LCM ....

I haven't taken a math class in ... 3 years. .____.
 
1. -4p - 3 = -2p + 7
-2p=10
p=-5

2. -3(m+2) - 2(m-1) = -2
-3m-6-2m+2=-2
-5m=2
m=-2/5
3. 1over3x + 1 = 2over3x - 4
(1/3)x-(2/3)x=-5
-(1/3)x=5
x=-15
4. 1-dover4 - dover2 = 7
1-d/4-d/2=7
-3d/4=6
d=-8
5. 4a+5over3 - 3aover2 = -a
5a= 3/2-5/3
5a=-1/6
a= -1/30

hope this helps.

On the first one, p is negative five. Number two, m is negative two-fifths. The rest, however, are confusing. On three, did you mean 1/(3x) and 2/(3x) or one-third times x and two-thirds times x or some mixture of the two? The same applies to the final two questions as your notation is very confusing. You need to find an acceptable tutor or the like or ask your math teacher for assistance.
