the answer is -17/1 or 17/-1
1. First you multiply by 10 to get rid of the decimals
3x - 5y = 12 and 7x - 2y = -1
2. Since we need to solve by elimation, we want to elimanate a variable. To do that multiple the first equation by 2 and the second equation by -5
6x - 10y = 24
-35x +10y = 5
3. Add the equations downwards
-29x = 29
4. Divide both side by -29
x= -1
5. Solve for y by putting -1 in for x into any of the equations. I'll use 3x- 5y=12
3(-1) -5y = 12
-3-5y=12
-5y =15
y= -3
For this case we must find the product of 
By definition, the distributive property states that:

Then, according to the expression we have:

Answer:

Option C
2% of 200 would be 4. You first <span>work out the difference between 2 and 200(200-2). Then you divide the difference by the original number and multiply the answer by 100. Your answer is 4
Hope this helps!</span>
Answer: Forgot to divide at the end
Step-by-step explanation:
To figure out your friend's error, solve the equation yourself.
- Distribute the 5 to get 25x+30
- Combine like terms in the first equation toget 25x-3=25x+30
- Add 3 to the other side.
When we do this, we realize adding 3 would make it 33. This shows that the friend likely forgot to divide by 25 to completely isolate x, and stopped at that step.
