Question

w+3>9

Answer 1

Subtract 3 from both sides.

Answer 2

\[W + 3 - 3 > 9 - 3\]

Answer 3

\[W > 6\]

Answer 4

You want to find the value of w, so you need it isolated on one side.
w + 3 > 9
If you subtract 3, you'll cancel out the +3. But you need to subtract from both sides of the equation for this to work.
w + 3 -3 > 9 -3
w > 9 - 3
As yahoo said, w > 6

Answer 5

Always keep the sign in front of the term.

For, -4 < t + 8 to cancel out and undo + 8, you subtract 8 from both sides.
-4 - 8 < t + 8 - 8
-12 < t

When you add the negative and positive value of a number, the sum is always 0.
(+)8 - 8 = 0
-8 + 8 = 0
