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
