MTH100 Assignment 2 Fall 2022 | Find the Value of “y” using the Crammer Rule

Question No.2 For the given system of equations find the value of “y” using the Crammer Rule. 2x+3y+z=2 x+3y+z=1 3x+y+z=3 Solution     Here 2x+3y+z=2 X+3y+z=1 3x+y+z=3     We have to find ‘y’     So, =2(3-1)-3(1-3)+1(1-9) = 2(2)-3(-2)+1(-8)=4+6-8=2 =2(1-3)-2(1-3)+1(3-3) = 2(-2)-2(-2)+1(0)=-4+4=0      So, by Cramer’s Rule
