First you need to determine how much standard deviation the range is.
120+12*x= 96
x= 96-120/ 12= -2
120+12*y=144
y= 144-120/12= +2
Systolic blood pressure between 96 mmHg and 144 mmHg means that the blood pressure is at -2SD to +2SD. The Z-score for -2SD is 0.0228 and +2SD is 0.9772
So the percentage would be: 0.9772- 0.0228 * 100%= 95.44%
