Question

Solve A = h (a + b) for b

Answer 1

how far did you get here?

Answer 2

can you work it out for me so i can see

Answer 3

you must undo everything that is being done to h. also yoou must do to one side what you do to the other. also you must start with whats being done to the b last (in this case you would first undo h) to undo multiplication (the h) you would?

Answer 4

First I would distribute the 'h' through, then I'd get everything but the b terms to one side by subtracting ha from both sides. Finally, divide both sides by h to isolate b.

\[\large A = h (a + b) \]

\[\large A = ha + hb \]

\[\large A - ha = hb \]

\[\large hb = A - ha \]

\[\large b = \frac{A - ha}{h} \]
