Question

Describe the condition that must be met in order to use Cramer’s rule.

Short answer

The required condition is that the denominator should not be 0.

Step-by-step solution

Step 1- Determine the factor that is related to the required condition

Determinant plays a major role for the application of Cramer’s rule as all the calculations are done through determinants.

– Analyze the obtained factor

The numerator and denominator of the value of each variable related to the determinants and if that determinant becomes 0 then the Cramer’s rule will not applicable in any circumstances.

Step 3- Make the conclusion

The required condition is that the denominator should not be 0.
