Let, the Age of Michelle = x
Age of Steve = x + 15
After 8 years, (x + 15 + 8) = 2(x + 8)
x + 23 = 2x + 16
2x - x = 23 - 16
x = 7
So, x + 15 = 22
In short, Age of Michelle is 7 & Age of Steve is 22 Years
Hope this helps!

Answer:
∠ SPQ = 75°
Step-by-step explanation:
The sum of the 4 angles in a quadrilateral = 360°
