If you have 2 apples and give away one apple, you have 1 apple left. 2 of anything minus one of the things leaves 1 thing.
2x- x= (2- 1)x= x.
Hi there. I was just wondering if anyone could perhaps just set me straight with this minor inequality question..
Inequality: 2x-3 ≦ 4+x
I said: 2x-x ≦ 4+3
2x ≦ 7 Solution: x ≦ 7
Now knowing the answer from an extra revision paper, The paper did not show that there is 2x left after I did 2x-x, Now I'd like to know does the 2 fall away in that case or..? Maybe I'm just not thinking straight right now from all the maths But could anyone please just explain it to me..
