Yolanda's was 25 years old when they were married.
Step-by-step explanation:
Let,
Age of Xavier = x
Age of Yolanda = x + 4
Combined age = 126
According to given statement;
Xavier's age + Yolanda's age = 126
[tex]x+(x+4)=126\\x+x+4=126\\2x=126-4\\2x=122\\[/tex]
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{122}{2}\\x=61[/tex]
Yolanda's age = x+4 = 61+4 = 65
Age when married = 65 - 40 = 25
Yolanda's was 25 years old when they were married.
