B(h+w)=4h(11-j), solve for w
frozen [14]

Answer:

W=4h(11-j)/b-h

Step-by-step explanation:

Eliminate variables on the left side first.

b(h+w) = 4h (11-j) - so, divide b by both sides

(h+w)/b=4h(11-j)/b  then, eliminate h by subtracting on both sides.

(h+w)-h=4h(11-j)/b - h   (h is eliminated on the left side and now you are left with

W=4h(11-j)/b - h
