Given the equation:
6(4.5y - 12) = 9
Solve the equation:
In order to solve the equation, we first need to distribute 6 to each value inside the parenthesis.
6(4.5y - 12) = 9
27y - 72 = 9
Transpose -72 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
27y = 9 + 72
27y = 81
Divide both sides by 27 in order to cancel out 27y, leaving behind y.
27y/27 = 81 / 27
y = 3
Final answer:
y = 3
