Ok, have another I can't  come up with an answer that works:( 4(x+3)=3x-10.  I got -22 which doesn't fit for X.  Can someone help me with this one please?

4x+12=3x-10
4x-3x+12=-10
x=-10-12
x=-22

good to me 

let check
4(x+3)=3x-10
4(-22+3)=3(-22)-10
4(-19)=-66-10
-76=-76
true


it works 
im guessing you made a calculation mistake

radar · Answer

Remove parenthese
4x=12+3x-10
Subtract 3x from both sides
x+12=-10 subtract 12 from both sides
x=-22, why do you say it doesn't fit for x substituting -22 for x in the original equations and check it out.
