The given expression is
14x - 14 > - 7x + 7
The first step is to add 7x to both sides of the inquality. it becomes
14x + 7x - 14 > - 7x + 7x + 7
21x - 14 > 7
The next step is to add 14 to both sides of the inequality. It becomes
21x - 14 + 14 > 7 + 14
21x > 21
Dividing both sides by 21, it becomes
21x/21 > 21/21
x > 1
