Haai!! =D

I have lots of homework due for tomorrow unfortunatlyy

And i've done half of what we're supposed to do, which is some of it, it's

2(5+2x) = 17

and my teahcer taught me to times the 2 to the 5 and the 2

which gives me

4x+10=17

then to do the same both sides by taking 10

so 4x = 7

then to divide both sides by 4 to give me the answer x=1.75 (hopefully, did that bit on a calculator)

Annnnnnnnyways....now i got like loads more to do, but they are different, and i don't understand how to work them out...the first and easiest one is

2x - 1 = x + 3

I really don't understand it...i really don't understand maths.

Can anyone help? Atall?

Thankss if you can and willl....i will love you =D
