The solution
You have entered
[src]
9*(3*x + 6) - 6*(7*x - 14) - 2*(x + 1) = 0
$$- 2 \left(x + 1\right) + \left(9 \left(3 x + 6\right) - 6 \left(7 x - 14\right)\right) = 0$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- 17 x = -136$$
Divide both parts of the equation by -17
We get the answer: x = 8
9*(3*x+6)-6*(7*x-14)-2*(x+1) = 0
Expand brackets in the left part
9*3*x+9*6-6*7*x+6*14-2*x-2*1 = 0
Looking for similar summands in the left part:
136 - 17*x = 0
Move free summands (without x)
from left part to right part, we given:
$$- 17 x = -136$$
Divide both parts of the equation by -17
x = -136 / (-17)
We get the answer: x = 8
