Use either the substitution or elimination method to solve the following word problem. Your answer should include two equations
vichka [17]
Let w represent the number of weeks passed.

The amount of money Ed saved is 6w - 1 (I'm subtracting the one dollar that he owes to someone)

His sister saved 6w + 2.66 (I'm adding the money she already saved).

What value of w makes both expressions equal?
We need to solve the equation 6w - 1 = 6w + 2.66

Let's solve it.
If we subtract 6w from both sides, we get -1 = 2.66
So, there is no solution. They will never have saved the same amount.
This makes sense because they started out with different amounts of money saved, but they are saving at the same rate.

Tina uses a $50 gift certificate to buy a pair of pajamas for 17.97 a necklace for 25.49 and 3 pairs of socks that each cost the
Furkat [3]
The overall cost is $50.33. you now subtract out the prices you know. The easiest way to do that is to add them up; 17.97+25.49. That is 43.46.

The next step is to subtract 43.46 from 50.33. 50.33-43.46=6.87. That is the price of all the pairs of socks put together.

to find out how much one pair is, you then divide 6.87 by 3. That is 2.29.

The answer is $2.29

I hope this helps!
