[src]
5*(x - 1) - 4*(x - 2) = 10
$$- 4 \left(x - 2\right) + 5 \left(x - 1\right) = 10$$
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:
$$x = 7$$
We get the answer: x = 7
5*(x-1)-4*(x-2) = 10
Expand brackets in the left part
5*x-5*1-4*x+4*2 = 10
Looking for similar summands in the left part:
3 + x = 10
Move free summands (without x)
from left part to right part, we given:
$$x = 7$$
We get the answer: x = 7
