If you were to divide numbers by 3, the ones that would give a remainder of 2 would be 1 number away from the next value I the multiplication table of 3 because 3 - 2 = 1. For example, 8 is a value that gives a remainder of 2 when divided by 3 because it is 1 less than 9. This means that your numbers are:
11, 14, and 17

Answer:
<u>x= -7 , y= 9</u>
Steps:
4x+3y=-1
5x+4y=1
First, multiply the top equations by -5, and the bottom by 4 to get :
-20x-15y=5
20x+16y=4
Then, you’re going to add the two equations with them being on top of each other so you can easily see what cancels out :
-20x-15y=5
+ 20x+16y=4
———————
0+1y=9
From this, you get :
y=9
Now that you have one variable, find x by substituting 9 for y in one of the equations, I choose :
4x+3y=-1
So :
4x+3(9)=-1
Then simplify by multiplying 3 and 9 :
4x+27=-1
Then subtract 27 on each side :
4x=-28
Then, divide by 4 to get that :
x= -7

Step-by-step explanation:
<u>Step 1: Define</u>
-2(x + 5) = -2(x - 2) + 5
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute -2: -2x - 10 = -2x + 4 + 5
- Add: -2x - 10 = -2x + 9
- Add 2x on both sides: -10 ≠ 9
Here we see that -10 does not equal 9.
∴ x = no solutions.
Answer:
2. 36
3. 8
4. 64 - 32
5. 7
I hope that this helps you, I'm not sure if number 4 is correct, but I am 100% sure that the rest are correct. I did the math for all of the questions and they should all be correct. I hope you have a wonderful evening!
