The discussion revolves around the algebraic expression -6(x+2)+10+3(x-3) and the participant's claim of arriving at the solution 9x+-11. Participants are attempting to clarify the steps involved in simplifying the expression and identifying where the misunderstanding may lie.
Participants generally disagree on the correctness of the initial solution of 9x+-11, with some asserting that the calculations leading to that result are incorrect. There is no consensus on the resolution of the misunderstanding, as different interpretations of the algebraic steps are presented.
Participants express uncertainty regarding the addition of terms and the interpretation of expressions versus equations, highlighting potential limitations in understanding algebraic operations.
i added -6x to 3x and got 9x so now i have 9x-12+10 - 9 is this correct?skeeter said:$-6(x+2) + 10 + 3(x-3) = -6x - 12 + 10 + 3x - 9$
now, combine like terms

why... this is what i was stuck on, i thought you add on both sides which is why i was getting 9xProve It said:-6x + 3x is not 9x, it's -3x.
How did you get -12 + 10 - 9 = -11 but not -6x + 3x = (-6 + 3)x = -3x? The addition of numbers works the same way!Calista A said:why... this is what i was stuck on, i thought you add on both sides which is why i was getting 9x
First "+-11" is not a number and makes no sense.Calista A said:this is a problem that i am working on -6(x+2)+10+3(x-3) in which i got the answer of 9x+-11 and apparently i am wrong, can someone help me understand this more.
