What are Simultaneous Equations (Linear and Quadratics)? Ever noticed a statement or an expression with alphabets and numbers written together? Something like: 6a + 5b = 4 In mathematics, we term such expression as equations. A statement in which two mathematical expressions like ‘6a' and ‘5b' are referred as equal. But these equations are not always singular. They can be in a set of two or more equations. SIMULTANEOUS EQUATIONS - When equations are presented in a set of two or more than two equations, we call them as simultaneous equations. Each equation shares their variables whose values need to satisfy the equations in the set simultaneously. Types of Simultaneous Equation Simultaneous equations are classified as Linear Equation or Quadratic Equation Let's briefly discuss each type. LINEAR EQUATION - A linear equation is also known as a first-degree equation, which means that the highest power of the variable in any linear equation is one. Even in the case of two variables, each variable of a linear equation has the power of one. For example; x + 9 = 5 in case of more than one variable, linear equations are written as: 5x + 2y + 6 = 1 Notice that the power of every variable is 1 QUADRATIC EQUATION - Unlike linear equations, quadratic equations have at least one variable squared, i.e., raised to the second power. For example: 6x^2 + 7y = 5 or 3a^2 + 4b^2 + 2 = 1
