Algebra, how do I solve for x?
« on: February 05, 2011, 04:15:42 PM »
2.5 = 1.25+x / 2.00-x

I am having trouble with this, it's part of an equilibrium problem. I cannot get past this step, help appreciated

$$2.5 = \frac{1.25+x}{2.00-x} /$$
$$2.5(2.00-x) = 1.25 + x /$$
$$5.00 - 2.5x = 1.25 + x /$$
$$3.75 = 3.5x /$$
$$x = 1.07 /$$
