Given the numerical equation:
14(2x + 8) = -16
Solve for x.
Solution:
In order to solve for x, we simply distribute 14 to each value inside the parenthesis.
14(2x + 8) = -16
28x + 112 = -16
Transpose 112 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
28x = -16 - 112
28x = -128
Divide both sides by 28, in order to cancel out 28x, leaving behind x.
28x/28 = -128/28
x = -4.57
Final answer:
x = -4.57
