Answer: 4x - 8
First, we use the property of distribution (its called something like that)
6 * x = 6x. 6 * 3 = 18. 6x - 18 - 2(x - 5)
We can also use the property of distribution on the other part.
2 * x = 2x. 2 * 5 = 10.
We then have the equation: 6x - 18 - 2x - 10.
18 - 10 = 8
6x - 8 - 2x
6x - 2x = 4x
4x - 8
