Based on BODMAS we will have to deal with the bracket first
6x+3y-12-2x-2y=10
To continue with the solution we will have to collect like terms
That is,
6x-2x+3y-2y=10+12
4x+y=22
This can't be solved further because we don't really know the value of x and y...it can only be solved further by knowing the value of either x or y but we are not given...so we will have to leave our final answer to be
Hello : <span>a single expression is : A = xy +zk x : </span> width1 y : <span>length1 z : </span>width2 k : <span>length2 A : </span><span>the total area of the two rooms note : A1 = xy ........</span>area of the room 1<span> A2 = zk </span>.......area of the room 2
