Your final equation would be 3(x+1)= 3x+3 because if you do 3 times x you get 3x so if you do 3 times 1 you get 3 making the equation have infinite solutions.
The final answer is: 3(x+1)= 3x+3 for an infinite number of solutions.
If x = # of quarters, then, the # of dimes will be equal to 2x. The total value (z) would be equal to:
z = 0.25x + 0.10(2x)
Then, since you switch the quarters and the dimes, and you have a new total, the resulting equation will be:
1.2 + z = 0.25(2x) + 0.10(x)
Plug in the values you know:
1.2 + (0.25x + 0.10(2x)) = 0.25(2x) + 0.10(x)
Solve for x:
1.2 + (0.25x + 0.20x) = 0.50x + 0.10x
1.2 + 0.45x = 0.60x
1.2 = 0.15x
x = 1.2/0.15 = 8
This means that there are 8 Quarters in her bag right now. So, the amount of dimes is just 2x which is 16. So your answer will be:
She has 8 Quarters and 16 Dimes in her bag right now. Or, $3.60.
If this doesn't make sense, then tell me. I have some resources where I got the answer from to put it into simplest terms. I have the website if you want.
Answer: 11x - y = 8x - y + 3x
Answer: The answer is C. ( 6, -5)
Step-by-step explanation:

Answer: 104</h3>
Explanation:
Convert the given fraction to decimal form 8/25 = 0.32
Then multiply it with the school population 0.32*325 = 104
We expect about 104 students walk to school
Note how 104/325 = 0.32, so 104/325 = 8/25
