w - 9 - (-1) > 3
To solve the inequality, we have to get w by itself on one side of the greater than sign, which will give us the answer. So we start by simplifying the left side of the equation. When you subtract a negative, you simply add, so the inequality becomes...
w - 9 + 1 > 3
Now combine like terms
w - 8 > 3
Now add 8 to each side to get w by itself
w > 11
This means that to keep the inequality true, w can be any number greater than 11.
