System of Linear Equations in Three Variables
A system of linear equations in three variables consists of equations such as that must all hold together. A unique solution is a triple satisfying every equation.
We usually solve it by elimination or substitution to reduce it step by step to a single variable.

Where it appears in Add Math
You meet System of Linear Equations in Three Variables 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 System of Linear Equations in Three Variables means but use it fluently in a full solution.
The term in three languages
Because the SPM Add Math paper is bilingual (BM/EN), it helps to know this term in each language: System of Linear Equations in Three Variables (EN) · Sistem Persamaan Linear dalam Tiga Pemboleh Ubah (BM) · 三元线性方程组 (中文)
