D

mathstudent55 · Answer

You want x alone.
2/7 is being subtracted from x.
You need to add 2/7 to both sides.

x - 2/7 + 2/7 = 3 + 2/7

mathstudent55 · Answer

The -2/7 and + 2/7 on the left side add to 0 leaving just x on the left side.
On the right side, you add 3 and 2.7 getting 3 2/7
The solution is
x = 3 2/7

In this case, 1/5 is being added to w.
You want w alone, so you need to subtract 1/5
Since you must do the same to both sides of an equation, you need to subtract 1/5 from both sides.
