The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by -3
We get the answer: x = 8
19+x = 4*(x-3)+7
Expand brackets in the right part
19+x = 4*x-4*3+7
Looking for similar summands in the right part:
19 + x = -5 + 4*x
Move free summands (without x)
from left part to right part, we given:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by -3
x = -24 / (-3)
We get the answer: x = 8
