x = 5
6x - 7 = 2x + 13
-2x +7 -2x + 7
4x = 20
(4x=20)/4
x = 5

Ah, algebra on a Sunday morning: don't you just love it.
1. Get rid of x from one side.
6x - 7 = 2x + 13 (-2x)
4x - 7 = 13
2. Add 7 to both sides
4x = 20
3. Divide both sides by 4 to give you your answer.
x = 5
And that's all there is to it.

x = 5
6x-7 = 2x + 13
6x-2x = 13 + 7
4x = 20
x = 20 divide by 4

8X - 7 = 2X + 13
if this is the right problem I an thinking of then
bring the 8X over the = and the 7 to the 13
then subtract ignore the X
once you have your answers then divide there you go
unless you have a x.xxxxxxxxxxx type number
then you have do something with your calculator
which I can't help you with because they all are different.
its been a long time so if I'm wrong just rate me down.

6x - 7 = 2x + 13
+7---------------+7
6x = 2x + 20
-2x -- -2x
4x = 20
/4 --- /4
x = 5

6x - 7 = 2x + 13
6x - 2x = 13 + 7
4x = 20
x= 5
I see a dot(.) if it is a decimal then
1.4x = -20
x = -20/1.4
= -10/0.7
and then find its value
