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:
$$6 x = 366$$
Divide both parts of the equation by 6
We get the answer: x = 61
3*x+3*(x+16) = 414
Expand brackets in the left part
3*x+3*x+3*16 = 414
Looking for similar summands in the left part:
48 + 6*x = 414
Move free summands (without x)
from left part to right part, we given:
$$6 x = 366$$
Divide both parts of the equation by 6
x = 366 / (6)
We get the answer: x = 61
