The value of x is 12 or 32
Y/x = 5 bc in order to isolate the variables you must divide by x on both sides to separate the 5, leaving you with y/x=5
we know that
The least
common multiple (LCM) of two or more numbers is the least
number, other than zero, that is a multiple of all the numbers.
In this problem, we are looking for the least common multiple of
and
So
Multiply
by 

therefore
On the
day after today, she will do both on the same day
the answer is

15y = 7x + 8
15y - 7x - 8 = 0
