(D) Given equations are:$2x + y = 17$ ....$(1)$$y + 2z = 15$ ....$(2)$$x + y = 9$ ....$(3)$Subtracting equation $(3)$ from equation $(1)$:$(2x + y) - (x + y) = 17 - 9$$x = 8$Substitute $x = 8$ into equation $(3)$:$8 + y = 9$$y = 1$Substitute $y = 1$ into equation $(2)$:$1 + 2z = 15$$2z = 14$$z = 7$Now,calculate the value of $4x + 3y + z$:$= 4(8) + 3(1) + 7$$= 32 + 3 + 7$$= 42$

If $2x + y = 17$,$y + 2z = 15$,and $x + y = 9$,then the value of $4x + 3y + z$ equals:
