Let siate age = x
And Kim aged = x + 9
Since kim age is one more than 3 times siate age
Therefore:
x + 9 = 1 + 3x
9 - 1 = 3x - x
8 = 2x
x = 4 (Siate age)
Kim age is 1 more than 3 times Siate age:
1 + 3x = 13 Kim age.
And Kim aged = x + 9
Since kim age is one more than 3 times siate age
Therefore:
x + 9 = 1 + 3x
9 - 1 = 3x - x
8 = 2x
x = 4 (Siate age)
Kim age is 1 more than 3 times Siate age:
1 + 3x = 13 Kim age.
