Answer 1

sorry friend.... I had tried

Answer 2

Answer:

Suppose Sara's age = X

So, Sara's Sister Ann age =  X-3

Mother age = Sara's age * 3 = X*3 = 3X

or = Ann's age * 4 = 4 ( X-3)

Step-by-step explanation:

Find the value of X

3X  = 4 (X-3)

3X= 4X-12

12 = 4X-3X

12 = X

X= 12

so Sara's age = X

Mother's age = 3X = 3 * 12 = 36

Anna's is age = X-3 = 12-3 =9
