2/5(x+1)=g. solve for x.

Question

anonymous · Answer

You would first multiply both sides by 5.
So, 2(x+1)=5g

hero · Answer

Hint:
$\large\frac{2(x+1)}{5} = g$

anonymous · Answer

she cant multiply by 5 since its a fraction. she has to mult the parenthesis by 2/5 instead

anonymous · Answer

Okay.. I got $$\frac{ 5g-2 }{ 2}$$ Is that wrong?

hero · Answer

Yup, that's right. And @magepker728, $\frac{2}{5}(x+1) = \large\frac{2(x+1)}{5}$   . Do you agree?

hero · Answer

It's easier to set up the right side then multiply both sides by 5 and continue solving from there. Some students do not feel comfortable multiplying by fractional inverses.

hero · Answer

@Victorialee seems to agree with me.

anonymous · Answer

I do! That is much easier that way.

phi · Answer

$$ \frac{5g-2}{2} $$ is correct.  But if it is multiple choice, be sure to know that you could also see it as
$$ \frac{5g}{2} -1 $$
or
$$ \frac{5}{2}g-1 $$

anonymous · Answer

a thumbs up for hero, as for me fraction is the way to go :D

hero · Answer

@magepker728, I take it that you're a student who is not a big fan of alternative methods. You tend to solve math problems exactly the way you were shown in school, correct?

anonymous · Answer

well I'm majored in computer science first year, and i tend to challenge myself specially with anything with fractions since not to many people love fraction. sorry if there is any error English isn't my first language.
