For positive value,
7x - 2 = 7
7x = 9
So, x > \(\frac{9}{7}\)
For negative value
7x - 2 = -7
7x = -5
So, x < -\(\frac{ 5}{7}\)
Therefore, Value of x must be, x > \(\frac{9}{7}\) or x < -\(\frac{ 5}{7}\); Only Answer choice E satisfiled .
Answer E.
7x - 2 = 7
7x = 9
So, x > \(\frac{9}{7}\)
For negative value
7x - 2 = -7
7x = -5
So, x < -\(\frac{ 5}{7}\)
Therefore, Value of x must be, x > \(\frac{9}{7}\) or x < -\(\frac{ 5}{7}\); Only Answer choice E satisfiled .
Answer E.

For this one, solving one case is enough as the options are such.
For positive value.
x > 9/7 = 1.28 approx....
Only option E is greater than 1.28 therefore, it has to be the answer since One Choice Answer.
For positive value.
x > 9/7 = 1.28 approx....
Only option E is greater than 1.28 therefore, it has to be the answer since One Choice Answer.
