A. y4x=3
11y=11
B.11y=3
7y+6x=11
C.4x+11y=5
11=11

so x from second equation will be x=23yz 2x+5y2z=1 3x2y+3z=17 hope that this is hence right,correct with 3z not with 3x before = so when x=23yz will get 2(23yz)+5y2z=1 3(23yz)2y+3z=17 46y2z+5y2z=1 69y3z2y+3z=17 y4z=3 11y=11 so from this result that y=1 so than 14z=3 so 4z=4 so z=4/(4)=1 so z=1 so than x=23(1)(1)=23+1=5+1=4 so x=4 x=4 y=1 z=1
