To find: The solution of equations using Cramer’s rule.

Answer to Problem 51PPS
The solution of the system is (4,8,−5) .
Explanation of Solution
Given,
The set of equation is given as,
3a−5b−9c=174a−3c=31−5a−4b−2c=−42
Calculation:
Calculate the determinant of x .
|x|=|17−5−9310−3−42−4−2|=17(0−12)+5(−62−126)−9(−124−0)=−28
Calculate the determinant of y .
|y|=|317−9431−3−5−42−2|=3(−62−126)−17(−8−15)−9(−168+155)=−56
Calculate the determinant of z .
|z|=|3−5174031−5−4−42|=3(0+124)+5(−168+155)+17(−16+0)=35
Calculate the determinant C .
|C|=|3−5−940−3−5−4−2|=3(0−12)+5(−8−15)−9(−16−0)=−7
Calculate the value of x, yandz.
x=−28−7=4y=−57−7=8
z=35−5=−5
Thus, the solution of the system is (4,8,−5) .
