The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Move the summands with the unknown x
from the right part to the left part:
$$8 x = 140$$
Divide both parts of the equation by 8
We get the answer: x = 35/2
22*x = 14*(x+10)
Expand brackets in the right part
22*x = 14*x+14*10
Move the summands with the unknown x
from the right part to the left part:
$$8 x = 140$$
Divide both parts of the equation by 8
x = 140 / (8)
We get the answer: x = 35/2
