Solving a System of Simultaneous Equations

The video tutorial explains how to solve simultaneous equations by manipulating them to have the same unknowns, either x or y. It emphasizes the importance of showing clear algebraic working to earn full marks. The process involves doubling one equation to match the y values, then adding or subtracting the equations to eliminate y and solve for x. Once x is found, it is substituted back into one of the original equations to find y. The tutorial concludes by explaining the marks allocation for each step.
