How to solve for x in this eq

Question

I'm doing a physics E&M problem, but I'm stuck on a math part. I can't remember how to solve for x in this instance.

${x\over 2} = {0.04-x\over 5}$

Answer 1

HINT:

1. Multiply each side of the equation by $10$.

2. Add $2x$ to each side of the equation.

3. Divide each side of the equation by $7$.

Answer 2

Solve it like any other algebra problem like this. Isolate $x$ to one side and then make the necessary multiplications.

Answer 3

$\frac{x}{2}=\frac{0.04-x}{5} \Rightarrow \frac{x}{2}+\frac{x}{5}=\frac{0.04}{5} \\ \Rightarrow \frac{7x}{10}=\frac{0.04}{5} \Rightarrow x=\frac{10}{7}\times \frac{0.04}{5}$
