Given the equation:

63 = 7 ( 5 + 7b )

Solve the given equation and find b.

Solution:

In order to solve the given equation, we simply need to distribute first, 7 to each value inside the parenthesis.

63 = 7 ( 5 + 7b )

63 = 35 + 49b

Transpose 35 to the other side of the equation, hence we must take note that in transposing a number, the sign changes.

49b = 63 - 35

49b = 34

Divide both sides by 49 in order to cancel out 49b leaving behind b.

49b/49 = 34/49

b = 34/49

Final answer:

b = 34/49
