I really need help - Solveing Equations
I am desperatly confused on this homework, we get it online @ MyMaths.co.uk - Bringing Maths Alive
I normally ask my dad, he has a maths degree but he is abroad and he doesn't come back till after I need this homework handed in.
This homework is in Monday, I know you may think it's not urgent now but Im away from Friday-Sunday night so I won't have time, I need to get it done, tonight!
Ok its about solving equations. These are the questions:
4x + 8 = 80 -4x
6x+11= -101 -8x
My sheet says you can use decimals if neccesary
Now I can do questions like this: 6x+32=8x+14. The answer would be x = 9 Is there any realation in that to the ones I can't do in bold?
I'm not asking for the answers, but could someone please explain to me step by step just how to do these questions in bold.
I would be really thankfull
If someone could help me out here, thanks.
