The solution
You have entered
[src]
3*(3*x - 4) + 6 - 5*x = 14
$$- 5 x + \left(3 \left(3 x - 4\right) + 6\right) = 14$$
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:
$$4 x = 20$$
Divide both parts of the equation by 4
We get the answer: x = 5
3*(3*x-4)+6-5*x = 14
Expand brackets in the left part
3*3*x-3*4+6-5*x = 14
Looking for similar summands in the left part:
-6 + 4*x = 14
Move free summands (without x)
from left part to right part, we given:
$$4 x = 20$$
Divide both parts of the equation by 4
x = 20 / (4)
We get the answer: x = 5
