Find the value of X so that the function has the given value.

q(x) = 1/2x - 3 ; q(x) = -4

well from the given functions of x we can say

1/2x-3=-4

=> 1/2x = -1

=> x = -2

so value of x = -2

hope it helps

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
