## anonymous 5 years ago find x, give your answer in fractions: x = 5 * (2-x) + 1

anyone who helps me will get a new fan :)

I know the answer is 1.83333333333 but i need it in fractions

3. anonymous

$x=5(2-x)+1\rightarrow x=10-5x+1$Add 5x to both sides,$6x=10+1 \rightarrow 6x=11$Divide both sides by 6,$x=\frac{11}{6}$

do i leave it like this, or do i have to make it like 1 5/6 ?

Depends...it doesn't really matter unless the question stipulates. Mathematicians leave fractions in this form - 'improper fraction' - because we'd have to put it into this form anyway to do any further mathematics on it. If you like, you can reduce it down to $x=\frac{11}{6}=\frac{6+5}{6}=\frac{6}{6}+\frac{5}{6}=1+\frac{5}{6}=1\frac{5}{6}$but I wouldn't bother.

ok, thanx, so in an exam i would just leave answers in improper fractions

Just check with your teacher on what they want you to do. Like I said, UNLESS the question says to do something with it, just leave it - 11/6 and 1+5/6 are equivalent numbers.
