Given the equation:
-5(x + 6) = 15
Determine the answer.
Solution:
In order to determine the answer, we simply need to distribute -5 to each value inside the parenthesis, and then combine similar terms.
-5(x + 6) = 15
-5x + 30 = 15
Transpose 15 and -5x to the opposite sides of the equation, hence it must be taken to note that in transposing a number, the sign changes.
30 - 15 = 5x
5x = 15
Divide both sides by 5 in order to determine the value of x.
5x/5 = 15/5
x = 3
Final answer:
x = 3
