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:
$$5 x = 5$$
Divide both parts of the equation by 5
We get the answer: x = 1
(3*x+5)+(2*x-7) = 3
Expand brackets in the left part
3*x+5+2*x-7 = 3
Looking for similar summands in the left part:
-2 + 5*x = 3
Move free summands (without x)
from left part to right part, we given:
$$5 x = 5$$
Divide both parts of the equation by 5
x = 5 / (5)
We get the answer: x = 1
