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:
$$4 x = 28$$
Divide both parts of the equation by 4
We get the answer: x = 7
(9*x-10)-(5*x-2) = 20
Expand brackets in the left part
9*x-10-5*x+2 = 20
Looking for similar summands in the left part:
-8 + 4*x = 20
Move free summands (without x)
from left part to right part, we given:
$$4 x = 28$$
Divide both parts of the equation by 4
x = 28 / (4)
We get the answer: x = 7
