Answer:
Theresa's height is 60 inches
Step-by-step explanation:
The given parameters are;
The height of Paul = The height of Steve
Paul's height = 
times Theresa's height - 16 inches
Steve's height = 
times Theresa's height - 6 inches
Let 'T' represents Theresa's height, we have;
Paul's height = ×T - 16
Steve's height = ×T - 6
Paul's height = Steve's height
Therefore;
×T - 16 = ×T - 6
×T - ×T = 10
×T - 
×T = 10
×T = 10
T = 10 × 6 = 60
Theresa's height, T = 60 inches
