Question

Solve for b.

a = a+b+c/3

A.) 3A - a - c = b
B.) -c / 3 = b
C.) A - c / 3 = b
C.) -3 - c = b

Answer 1

letter A.

Answer 2

We have
\[a=a+b+\frac c3\]
Subtract both sides by a
\[a-a=a-a+b+\frac c3\]
We get
\[0=0+b+\frac c3\]
now subtract both sides by c/3
\[0-\frac c3=b+\frac c3-\frac c3\]
we get finally
\[-\frac c3=b\]

Answer 3

a=a+b+c/3 3a-a-c=b

Answer 4

Thank You!

Answer 5

Pass the a that is in the denominator multiplying the letter "a"
