-- You select an operation.
-- You apply the same operation to each side of the equation.
-- You keep doing both steps until the equation says
(the variable) = (the value of the variable)
Its called Simultaneous Equations

12 h = - 72
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 .

You need not have x in an algebraic equation. You solve whichever one is the easiest and that depends on the set of equations that you have.
Algebraic inequalities can be solved in the same fashion as algebraic equations. The goal here, as in algebraic equations, is to isolate the variable. The one thing to remember, however, is that when dividing or multiplying both sides by a negative number, one must switch the inequality sign.
You solve algebraic expressions by getting the variable by itself.
algebraic equations that require 2 or more steps to solve. ex: 3(x - 2) = x + 8
Finding the point of intersection using graphs or geometry is the same as finding the algebraic solutions to the corresponding simultaneous equations.

Numerical equations have only numbers and symbols, while algebraic equations have variables also.
