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:
Divide both parts of the equation by 4
We get the answer: x = 3
2*x+2*(x+7) = 26
Expand brackets in the left part
2*x+2*x+2*7 = 26
Looking for similar summands in the left part:
14 + 4*x = 26
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 4
x = 12 / (4)
We get the answer: x = 3
