Use the matrix tool to find the solution to the system of equations. Enter the
y-value of the solution in the box below.
x+ y+ z = 2
y- 3z = 6
2x - 3y+ z= 6

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
