Substitution Method
The substitution method solves simultaneous equations by making one variable the subject of the linear equation, then replacing it in the non-linear equation. This leaves a single equation in one unknown, often a quadratic, which we solve before finding the matching value of the other variable.

Where it appears in Add Math
You meet Substitution Method in the Systems of Equations chapter of SPM Additional Mathematics. Knowing the term precisely matters in the exam: questions often hinge on reading a keyword correctly, and because SPM marking is analytic, using the right definition in your working helps secure method marks.
Our teachers make sure a student can not only recite what Substitution Method means but use it fluently in a full solution.
The term in three languages
