Determinants all formula
WebLong story short, multiplying by a scalar on an entire matrix, multiplies each row by that scalar, so the more rows it has (or the bigger the size of the square matrix), the more times you are multiplying by that scalar. Example, if A is 3x3, and Det (A) = 5, B=2A, then Det (B) = 2^3*5=40. Det (kA)=k^n*Det (A). Webx = D x D, x = D x D, y = D y D. y = D y D. Step 5. Write the solution as an ordered pair. Step 6. Check that the ordered pair is a solution to both original equations. To solve a system of three equations with three variables with Cramer’s Rule, we basically do what we did for a system of two equations.
