The solution
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:
$$x = -15$$
We get the answer: x = -15
7*x-3*(2*x-5) = 0
Expand brackets in the left part
7*x-3*2*x+3*5 = 0
Looking for similar summands in the left part:
15 + x = 0
Move free summands (without x)
from left part to right part, we given:
$$x = -15$$
We get the answer: x = -15
