4w+4>8\times 4
Multiply both sides by 4. Since 4 is positive, the inequality direction remains the same.
4w+4>32
Multiply 8 and 4 to get 32.
4w>32-4
Subtract 4 from both sides.
4w>28
Subtract 4 from 32 to get 28.
w>\frac{28}{4}
Divide both sides by 4. Since 4 is positive, the inequality direction remains the same.
w>7
Divide 28 by 4 to get 7.
