Solve the inequality 2(2x − 4) > 28

2(2x-4)>28In this question we want the get the x on it's own so we need to remove everything beside it.So we multiply out the brackets 2(2x-4) = 4x-8So then we have 4x-8>28.Then we move the 8 to the other side which becomes an addition giving us 4x>28+8 which is 4x>36And now we move the 4 over to the other side and it becomes a divide. x>36/4This gives us an answer of x>9.
