The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Looking for similar summands in the right part:
Move the summands with the unknown x
from the right part to the left part:
$$10 x = 20$$
Divide both parts of the equation by 10
We get the answer: x = 2
-5*x = 15-5*(3*x-1)
Expand brackets in the right part
-5*x = 15-5*3*x+5*1
Looking for similar summands in the right part:
-5*x = 20 - 15*x
Move the summands with the unknown x
from the right part to the left part:
$$10 x = 20$$
Divide both parts of the equation by 10
x = 20 / (10)
We get the answer: x = 2
