First, we'll move the brackets from the right side, to the
left side. For this reason, we'll subtract the product 7(-2-11x) both
sides:
-8(4+9x) - 7(-2-11x) = 7(-2-11x) -
7(-2-11x)
We'll eliminate like terms from the right
side:
-8(4+9x) - 7(-2-11x) =
0
Now, we'll remove the
brackets:
-32 - 72x + 14 + 77x =
0
We'll combine like terms:
5x
- 18 = 0
We'll isolate x to the left side. For this reason,
we'll add 18 both sides:
5x - 18 + 18 =
18
We'll eliminate like
terms:
5x = 18
We'll divide by
15 both sides:
x = 18/5
x =
3.6
The solution of the equation is x =
3.6.
