Simultaneous Linear Equations
Bayani Gaba-gaba
Some problems involve two unknowns connected by two conditions. A pair of simultaneous equations captures both conditions at once, and solving the system gives the unique values that satisfy both. This is one of the most useful algebraic techniques in the specification.
You will learn two methods for solving linear simultaneous equations: elimination and substitution. Higher-tier students also connect the algebra to the point where two straight lines cross on a graph.
Manufura
- Calculate the exact solution of two simultaneous equations in two unknowns
- [Higher] Interpret the equations as lines and the common solution as the point of intersection
