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

Move the mouse over a dotted box for more information.

Now you try. Try solving a linear equation. After that, try solving two equations with two unknowns (that is a "system of equations").

See your results here:

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 $u$.
