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:
$$3 x = 15$$
Divide both parts of the equation by 3
We get the answer: x = 5
-5*x = 11-2*(4*x-2)
Expand brackets in the right part
-5*x = 11-2*4*x+2*2
Looking for similar summands in the right part:
-5*x = 15 - 8*x
Move the summands with the unknown x
from the right part to the left part:
$$3 x = 15$$
Divide both parts of the equation by 3
x = 15 / (3)
We get the answer: x = 5
