How to solve a simultaneous equation
WebSimultaneous equations are two or more algebraic equations that share common variables and are solved at the same time (that is, simultaneously). For example, equations x + y = 5 … WebThe method for solving simultaneous equations with variable x and y is: First rearrange one equation to obtain an expression or a value for x. The rearranged equation may be x = a number, or it may be an expression where x = a function of y (i.e. y still exists as an unknown in the equation).
