Solving equations always comes up in many areas of math, so we've developed a function called

The

`solve`

that knows how to
solve linear equations. Linear equations are equations where the exponents of the variables you want to solve for are always one ($1$).
The

`solve`

function works like this:
answer=solve("your-equations","variables-to-solve-for")

This example will solve $4x-3y=-3$ for $x$. You might also try:

- Solving $5x+3y=6$ and $2x-4y=5$ for $x$ and $y$.
- Solving $2a+5b=3$ and $2a+b=9$ for $a$ and $b$.
- $u+4u=56$ for $u$.
