## Quick Start

```js
var expr = new Expression("x");
expr = expr.subtract(3);
expr = expr.add("x");

console.log(expr.toString());
```

```
2x - 3
```

```js
var eq = new Equation(expr, 4);

console.log(eq.toString());
```

```
2x - 3 = 4
```

```js
var x = eq.solveFor("x");

console.log("x = " + x.toString());
```

```
x = 7/2
```
