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=2x-14
6+x-x=2x-14-x
6=1x-14
6+14=1x-14+14
20=1x
20/1x=1x/1x
x=20
1.25 of 64
6+x=2x-14
-x = -x
6=x-14
6+14=+14
20=x
