Rearrange the equation so that it equals Q
3Q-Q = 4 + 6
2Q = 4 + 6
Q = (4 + 6)/2
Q = 5

Q + 4 = 3Q - 6
To solve this, move everything with a Q in it to the left hand side, and move everything else to the right hand side. Note that the sign of the term changes upon switching sides; 3Q, for instance, will become -3Q, and +4 will become -4. Therefore, we get
Q - 3Q = -4 - 6
Now, group like terms. Q - 3Q is equal to -2Q, and -4 - 6 is equal to -10.
-2Q = -10
Now, to isolate the Q, divide both sides by (-2). This will leave you with just Q on the left hand side.
Q = (-10) / (-2)
-10 divided by -2 is equal to 5, so
Q = 5

Q+4=3Q-6
Add 6 to both sides:
Q+4+6= 3Q-6+6
Q+10=3Q
Then subtract Q from both sides:
Q+10-Q =3Q-Q
10=2Q
Now divide both sides by 2:
10/2 =2Q/2
5=Q
Done.

get all the Q's on one side and all the numbers on the other
Q + 4 = 3Q - 6
first subtract Q from both sides to get
Q - Q + 4 = 3Q - Q - 6
which is
4 = 2Q - 6
than add 6 to both sides
4 + 6 = 2Q - 6 + 6
to get
10 = 2Q
and finally divide both sides by 2
10/2 = 2Q/2
to get the answer
Q = 5

This is basic algebra...
Step 1:
Move 3Q to the left...
Q+4 - 3Q = 3Q-6 - 3Q
-2Q+4 = -6
Step 2:
Move the 4 to the right...
-2Q+4 - 4 = -6 - 4
-2Q = -10
Step 3:
solve for Q by dividing by -2...
-2Q/-2 = -10/-2
Q = 5
Voila!
Hope this helps! :)

Q+4=3Q-6
4 + 6 = 3Q - Q
10 = 2Q
10/2 = Q
5 = Q
Q = 5

q+4=3q-6 (add 6 from each side)
q+10=3q (substract q from each side)
10=2q (divide by 2)
5=q

Q+4=3Q-6
-Q = -Q (Subtract 1Q from both sides)
4= 2Q-6
+6= +6 (Add 6 to both sides)
10=2Q
5=Q (Divide both sides by 2)
