Answer: The answer is B

Step-by-step explanation: 122 >7 (z+8) -5 (6+z). Then switch them, 7 (z+8) -5 (6+z) <122. Expanded:  7 (z+8) -5 (6+z) <122:v 2z+26

2z+26<122, subtract 26 from both sides: 2z+26-26<122-26

Simplify: 2z<96, divide both sides by 2: 2z over 2 < 96 over 2

and finally simplified: Z<48

HOPE THIS HELPED YOU OUT!
