Chelsea shows her work in finding the solution to 4x-5=2+3(x-3). After checking her answer in the original equation, she found t
hat it did not work. Where did she make a mistake?

Answer: x = -2, it could be they didnt follow the right order of mathematic operation (BODMAS)
Step-by-step explanation:
4x-5 = 2+3(x-3)
following the order of operation we must open the bracket first
4x - 5 = 2 + 3x - 9
4x - 5 = 3x - 7
we now collect like terms
4x - 3x = -7 + 5
x= -2
Now checking the answer in the original equation, we will just put -2 wherever x is.
4x - 5 = 2 + 3(x-3)
4(-2) - 5 = 2 + 3( -2 -3)
We will have to deal with the bracket first before we proceed;
-8-5 = 2 + 3(-5)
-13 = 2 - 15
-13 = -13
Answer:
The solution is x=-2
The mistake could be in operation however here is the all operation
Step-by-step explanation:
Getting each term and sum each one
Check replacing in the original equation:

Answer: x=2 and y=−6
Step-by-step explanation: 2x+y=−2, 5x+3y=−8
2x+y=−2
2x+y+−2x=−2+−2x
y=−2x−2
5x+3y=−8
5x+3(−2x−2)=−8
−x−6+6=−8+6
−x=−2

y=−2x−2
y=(−2)(2)−2
y=−6
x=2 and y=−6
No i am horrible in it and everytime i come to ask questions nobody helps :(
It's the first one and the last one need any more help let me know okay
Yes, because
Hope that helped :D
