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:
$$5 x = 30$$
Divide both parts of the equation by 5
We get the answer: x = 6
-4*x = 15-3*(3*x-5)
Expand brackets in the right part
-4*x = 15-3*3*x+3*5
Looking for similar summands in the right part:
-4*x = 30 - 9*x
Move the summands with the unknown x
from the right part to the left part:
$$5 x = 30$$
Divide both parts of the equation by 5
x = 30 / (5)
We get the answer: x = 6
