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:
$$- 2 x = -150$$
Divide both parts of the equation by -2
We get the answer: x = 75
8*x = 10*(x-15)
Expand brackets in the right part
8*x = 10*x-10*15
Move the summands with the unknown x
from the right part to the left part:
$$- 2 x = -150$$
Divide both parts of the equation by -2
x = -150 / (-2)
We get the answer: x = 75
