=
𝐵
AX=B

How to compute the inverse of the coefficient matrix (when it exists)

How to apply the formula

B to find the solution matrix

Worked examples tailored to Form 4 level — perfect for KCSE prep

Why Watch This Video:

The matrix method simplifies complex simultaneous equations and is an invaluable skill for both the exam room and further studies. Whether you're tackling 2x2 systems or expanding to more variables, this video gives you clarity and confidence.

Example Flow (Topics You’ll See):

Write equations in standard form

Form the coefficient matrix A, variable matrix X, and constant matrix B

Calculate A⁻¹ (inverse of A) — include determinant and adjugate steps

Multiply A⁻¹ * B to get X — which yields the values of the variables
