Answer 2

Divide the whole equation by (B+C)

Answer 3

So we get :

Answer 4

The RHS is 3 , right?

Answer 5

Answer 7

So we get:
\[\frac{ A }{ B+C } = 3\]

Answer 8

We'll start again,okay?

Answer 9

ok

Answer 10

This time we divide the whole equation by 3.
\[\frac{ A }{ 3 } = \frac{ 3(B+C) }{ 3}\]

Answer 11

That gives

\[\frac{ A }{ 3 } = B+C\]

Answer 12

Move C to the other side.

Answer 13

okay

Answer 14

\[\frac{ A }{ 3 } - C = B\]

Answer 15

Solve the above equation.

Answer 16

\[\frac{ A - 3C }{ 3 } = B\]

Answer 17
