Ответ:
45 years old
Step-by-step explanation:
Suppose Dianna age 33 years ago = x
Dianna age today = x + 33
Dianna age after 3 years = (x + 33) + 3
In 3 years, Dianna will be 4 times as old as she was 33 years ago
Equation
4x = (x+33) + 3
4x = x + 36
4x - x = 36
3x = 36
x = 36/3
x = 12
Dianna age today = x + 33 = 12 + 33 = 45
Diana is 45 years old.
