So we have this inequality 7x + 2 > 30 and in order to solve it we need to find the value of X.
In this case lets try to put the numbers on one side of this inequality and the unknown values on the other side. The numbers and the x-s that will switch sides will also change their sign from a + to a - and vice versa and this will not affect the inequality sign, so it will stay like this >.
7x > 30-2
7x > 28
Lets try to divide both sides with 7. 7 is a positive number because 7>0 so the sign will not change this time as well.
7x/7 > 28/7
x>4
