Question 883006
Hello!
***
First off, let me thank you for letting us know how far you got; it is really helpful for us in allowing us to gauge where you are. =)

Your initial set up is correct; you just got a little off when you were trying to solve.
{{{2(-2 + x) = x - 1/2}}}
Distribute: {{{-4 + 2x = x - 1/2}}}
Subtract x from both sides: {{{-4 + x = -1/2}}}
Add 4 to both sides: {{{x = 4 - 1/2}}}
Find a least common denominator: {{{x = 8/2 - 1/2}}}
Subtract: {{{x = 7/2}}}
Therefore, the answer is {{{7/2}}} (as you said).

I hope this helps!
