Aug 16, 2015 · How do I use Cramer's rule to solve a system of equations? Precalculus Matrix Algebra Cramer's Rule. 1 Answer Ernest Z. Aug 16, 2015 You divide each variable determinant by the determinant of the coefficients. EXAMPLE: Use Cramer's Rule Terms; Help Rule 1. If ∆ ≠ 0.Then the system has unique solution and we can solve the equations by using the formula x = ∆ ₓ /∆ , y = ∆ ᵧ /∆ Examples. Rule 2. If ∆ = 0 and ∆ₓ= 0, ∆ᵧ= 0 and at least one of the coefficients a₁₁,a₁₂,a₂₁,a₂₂ is non zero,then the system is consistent and has infinitely many solution.
