You solve algebraic expressions by getting the variable by itself.

meaning to evaluate the variable in an expression. An algebraic expression is also a problem that contains no equals sign and you don't solve it, rather you simplify it.It means to solve something.

The Cartesian system allows you to describe a geometric shape in algebraic terms. This allows algebraic techniques, such as differentiation or integration to be applied to solve problems in geometry. Conversely, geometrical results can be used to solve problems in algebra.

you apply the Laplace transform on both sides of both equations. You will then get a sytem of algebraic equations which you can solve them simultaneously by purely algebraic methods. Then take the inverse Laplace transform .
