6+x=2x-14

First get the unknown quantitites on one side of the equation. Subtract x from both sides.

6 + x = -14

Then get the known quantities on the other side. Add 14 to both sides.

20 = x

6+x=2x-14

Letters on one side, numbers on the other. Subtract x from both sides.

6=x-14

Add 14 to both sides.

20=x

6+x=2x-14

6+x-x=2x-14-x

6=1x-14

6+14=1x-14+14

20=1x

20/1x=1x/1x

x=20

-x = -x

6=x-14

6+14=+14
