For these questions it's asking you to substitute the value into the equation.
For example question 5 says,
26= y-9;y=35
basically it's saying if y=35, is the equation correct or not.
In this case: 26= 35 -9 is correct.
So your answer is true.
Hope this helps Xx
I’m doing this too hopefully someone answers quick cause I’m confused also.
Answer:
Before going to the first store he had $ 112.
Step-by-step explanation:
Before going to the first store Mr. Chin had all his money, which we will call by "x". After the first store he had:
y = x/2 - 14
He then went to a second store and he spent all his money in a way that:
y/3 - 14 = 0
Because after that store he had no money left. So we can use the second equation to solve for y and then use that value to solve for x, that is the amount of money he had before going to the first store. We have:
y/3 = 14
y = 14*3 = 42
From the first equation:
42 = x/2 - 14
x/2 - 14 = 42
x/2 = 42 + 14
x/2 = 56
x = 112
Before going to the first store he had $ 112.

So the first thing you want to do is see how much quarts are in a gallon. (4.) Then you figure it would need 2 eight packs to get 4 gallons, as there are 8 quarts in each. 2 eight packs would cost 32 dollars verses 24 dollars for a 4 gallon jug (the same amount as 2 eight pack quarts.) So the 4 gallon jug is cheaper.
