The solution
You have entered
[src]
4*(2*x - 1) + -3*x - 4 = 5*x - 8
$$\left(- 3 x - 4\right) + 4 \left(2 x - 1\right) = 5 x - 8$$
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:
$$5 x = 5 x$$
Move the summands with the unknown x
from the right part to the left part:
$$0 = 0$$
This equation is the identity and the solution: any x
4*(2*x-1)-(3*x+4) = 5*x-8
Expand brackets in the left part
4*2*x-4*1-3*x-4 = 5*x-8
Looking for similar summands in the left part:
