The solution
You have entered
[src]
20*x + 5 - 6*x - 4 = 30
$$\left(- 6 x + \left(20 x + 5\right)\right) - 4 = 30$$
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$14 x = 29$$
Divide both parts of the equation by 14
We get the answer: x = 29/14
20*x+5-6*x-4 = 30
Looking for similar summands in the left part:
1 + 14*x = 30
Move free summands (without x)
from left part to right part, we given:
$$14 x = 29$$
Divide both parts of the equation by 14
x = 29 / (14)
We get the answer: x = 29/14
