Solve the equation:

\[ 15 = -3(2x - 1) \]

How do you solve this problem?

15=-3(2x-1)
15=-6x+3
6x=3-15
6x=-12
x=-12/6=-2.

15 = -3(2x - 1) 15 = -3 2x -3 (-1) 15 = -6x + 3 15 - 3 = -6x |*(-1) -12 = 6x |:6 x = -2
The solution of this equation is very simple. Simply move an unknown to one side, and known to the other. Then the number of the right divided by the number of standing by the unknown and this is the result.

To solve the equation 15 = − 3 ( 2 x − 1 ) , first distribute -3, leading to 15 = − 6 x + 3 . Then isolate x by first moving terms and finally divide to find x = − 2 . A quick check confirms that this solution is correct.
