Answer:

After 6.2 months Isabella weight will be same as Gary weight.

Explanation:

Given:

Weight of Gary = 184 pounds

Losing pounds per month = 4

Weight of Isabella = 215 pounds

Losing pounds per month = 9

We need to find how many months it take for Isabella to weight to same as Gary.

Solution:

Let the number of months be denoted by 'x'.

So we can say that;

Weight of Gary after x months will be equal to Weight of Gary minus Weight losing per month multiplied by number of months.

framing in equation form we get;

Weight of Gary after x months =
184-4x

Weight of Isabella after x months will be equal to Weight of Isabella minus Weight losing per month multiplied by number of months.

framing in equation form we get;

Weight of Isabella after x months =
215-9x

To find the number of months when both weight will be same we need to make both the equation same.

So we can say that;


184-4x=215-9x

Combining like terms we get;


9x-4x=215-184\\\\5x= 31

Dividing both side by 5 we get;


(5x)/(5)=(31)/(5)\\\\x= 6.2 months

Hence After 6.2 months Isabella weight will be same as Gary weight.
