Graphical solution of equations igcse
WebIf we have one equation and one unknown/variable, we can solve the equation (eg 2x + 1 = 9). When we have two unknowns/variables we need two equations to find both their values. In that case we are solving two equations simultaneously (at the same time). In the past we have learned two strategies to do so successfully; the substitution and the ... WebOne way to solve simultaneous equations is by plotting them both on a graph and finding the point where they cross. The coordinates of this point will be the solution to your question. Show...
